Still have the realtimeconfigquickscan files in my ~/ . It’s been so long since I ran this that I forgot it was a perl script and was bashing it with python. Anyway for Nick, you will want to find the irq# of your soundcard, you can easily find it by running command
cat /proc/interrupts
, for example myinbuilt souncard is a hda_ model so was easily enough found. then in the terminal run export SOUND_CARD_IRQ=( then the number from the cat /proc/interrupts without these brackets obviously ) , then make sure to keep this terminal open as the export command only lasts as long as that terminal is open AFAIK, run the perl quickscan script. phew, that was not easy for me to explain

Sorry Nick if this all seems a lot to deal with, I will try and slow it down a bit… think I’m just excited for you to get this fixed is all
if you could paste the output of the following files too please … They may all not exist. remember to use the command clear each time in the terminal to keep things tidy for yourself.
cat /proc/asound/cards
cat /proc/asound/modules
lsmod
cat /etc/alsa/conf.d/*
cat /etc/asound.conf
cat ~/.asoundrc
cat /etc/modprobe.d/alsa-base.conf
I actually remember a lot of these files from years ago when I was having Audio troubles myself

an idea, run renoise with pulseaudio suspended padsp renoise and just incase, have a look at the output settings in pavucontrol

No problem at all, I appreciate the help from you both!
Okay I’ve tried: appending “nick - memlock unlimited” to limits.conf, setting nice to -19 down from -10, restarting my laptop then running Renoise and have the same result.
This is the output when I run the command you mentioned:
nick@nick-MacBookPro:~$ groups && cat /etc/security/limits.d/audio.conf
nick adm cdrom sudo dip plugdev lpadmin sambashare
# Provided by the jackd package.
#
# Changes to this file will be preserved.
#
# If you want to enable/disable realtime permissions, run
#
# dpkg-reconfigure -p high jackd
@audio - rtprio 95
@audio - memlock unlimited
#@audio - nice -19
I found the irq of the soundcard in /proc/interrupts/, ran the export command you listed and then ran rtcqs. The result is below:
nick@nick-MacBookPro:~$ export SOUND_CARD_IRQ=74
nick@nick-MacBookPro:~$ ./Applications/rtcqs/rtcqs.py
rtcqs - version 0.3.1

I also tried running renoise from the terminal using padsp renoise and had the same issue. The output config from pavucontrol is below:
Also, apologies but I accidentally clicked the “Solution” button while bouncing between windows pasting in the terminal output. I unchecked it for now, but will re-check when we figure it out.
@nick Wow it must have taken you some considerable time to go through all of those commands and to log it all here, kudos to you!!
OK You definitely have some issues regarding having a fully low latency audio experience from the output of the realtimeconfig scan, but these are certainly not what is causing the issue you face.
{[ We can come back to this when you get Renoise up and running }].
The output of groups && cat /etc/security/limits.d/audio.conf shows me that you are not in the audio user group which might not be OK. I’m starting to think, or at least with me having similar files and according to the command ulimit -a , my settings are being read from the audio.conf file before/instead of the limits.conf file . Interesting that I’ve never noticed this before, I’ll have to do a reboot here just to check.
We will go through these 1 by 1 , I’ll be right back .So don’t do anything in the meantime
EDIT// forgot to ask if you could paste the output of ulimit -a this will show if you are set up correctly and you shouldn’t have to try my commands in the post below EDIT//
Ahhh Interesting I was right about this part above, the audio.conf file takes 1st priority. For now if you could could add yourself to the audio group and reboot, once again trying Renoise to see if this is an issue 1st. Thanks
sudo usermod -a -G audio nick
Okay just gave it a shot and still having the same problem. I re-ran rtcqs and confirmed that I’m now in the audio group, screen here:
Just to re-check, I tried playing an audio file in Reaper using Alsa and it worked fine, so at least the tweaks we’ve made still work for other programs.
Output for ulimit -a here as well!

Ok good work, at least we have ruled out the priorities being the issue here. [ at least you have all your changes documented here, so reverting back will be no problem if required ] .
The 2nd thing that I was initially worried about was do you have the correct modules loaded for your soundcard ?, but I’m guessing by looking at your output of your lsmod you are covered ( it’s hard to know for sure as your drivers are different than mine ‘snd_hda_intel’ so I can’t truly compare. I guess you would have no sound if the driver wasn’t loaded.
There are a couple of basic steps you could dig into, just to clear them up before we dive deeper into this…
(1) in alsamixer when you press f6 what all options are shown?
(2) with pavucontrol open and Renoise playing a song, are you seeing anything in the playback tab ? ( I want to try and rule out Alsa playing through or rather being blocked somehow by pulseaudio )
(3) What options are shown in pavucontrol configurationtab > Profile ?
(4) With Renoise running open a terminal and do command killall pulseaudio use the up arrow key after pressing enter to repeat the command until any instances are killed, to easily reload the daemon simply run pulseaudio -D
Next when we eliminate these things, I want to look at your alsa settings, I have a few ideas on troubleshooting that.

Can you try Reaper with Jack if it works? And then close reaper and open Renoise and connect it to Jack. It’s really strange that there’s no sound from Renoise.
Is there maybe an issue with the output of the master channel?

@lilith Great idea. It has to be something simple blocking/kicking the audio from Renoise.
I really hope this is the issue, I’m sure it could be accidentally changed to an output that doesn’t exist

When I press f6 in alsamixer I get three options: “-” for default, “0” for HDA Intel HDMI, and “1” for HDA Intel PCH. I get the same options in Renoise and have tried all the available output channels. In other programs (Mixxx, Reaper) the PCH card works when selecting PCH Analog output.
-
While I’m playing one of the demo songs in Renoise, it’s not listed in the playback tab of pavucontrol (just “System Sounds”).
-
In the pavucontrol configuration tab (with Renoise playing) there are two entires for “Built-in Audio”, one with the Profile set to “Off” and one set to “Analog Stero Duplex”. My guess is the first is the HDMI sound card as all of the options have HDMI in them, the second has a lot of options: Analog Stereo Duplex, Analog Stereo Output, Digital Stereo Input/Output, Analog Surround 2.1 Input/Output, and Analog Suround 4.1 Input/Output.

With Renoise running, after I kill pulseaudio and try to restart it I get the below message, is that expected?
nick@nick-MacBookPro:~$ killall pulseaudio
pulseaudio: no process found
nick@nick-MacBookPro:~$ killall pulseaudio
pulseaudio: no process found
nick@nick-MacBookPro:~$ pulseaudio -D
E: [pulseaudio] main.c: Daemon startup failed.
@lilith right now Reaper doesn’t work with Jack but does with Alsa. This is my first time using Jack though so I likely don’t have it set up correctly. I’m working on getting Reaper to work with Jack and if that works will try to use the same setup with Renoise.
For output, I checked that first based on this thread. The master output has two options one for channels 1+2 and for channels 3+4. Neither seem to work yet. Here’s a screenshot of what it looks like:
Ok @nick , as always a great detailed reply.
For:-
(1) Choose HDA Intel PCH. ( could you also screenshot alsamixer to see what controls that you have, if there are any changes ? )
Might not be necessary, but I use the esc key to close alsamixer instead of just closing the terminal ( can’t remember if I read that somewhere or why I do this, but I think it always best to exit a terminal as cleanly as possible when closing an app ).
(2) Seems to be the expected behaviour.
(3) choose duplex mode here ( what was it already set to ? )
(4) hmm this is a tricky one, there could be one of many factors causing this.
Do you have pulseaudio set to not autospawn?
When you were using systemctl before for pulseaudio did you revert those settings?
can you paste the command/s you used please ? they will be in your bash history
history | grep systemctl
Another possibility is that your sound issues, or more so Renoise is blocking pulseaudio somehow, or basically locking up your soundcard.
I have an idea … would you create this following file by running this command
echo -e "defaults.pcm.card 1\r\ndefaults.pcm.device 1" >> ~/.asoundrc
…And restart alsa, or maybe even reboot just to be sure… and obviously try Renoise again. And maybe test other alsa audio apps like reaper lmms etc, antyhing that lets you choose direct alsa
1 Like
If non of the above works …
A good way to test if this is a system config problem or just the Renoise doesn’t play nice with your particular soundcard would be to run a live distro from usb and install Renoise in the live environment .
If I remember correctly you can do this in the live usb without having to set it up with persistence.
I’d recommend Ubuntu-20.04 for a starter.
It might even be possible to cd to your existing renoise binary directory and run it, without having to install it?

Here is a screenshot of what I see when I select HDA Intel PCH. This is with my headphones unplugged. Also noted that I always exit before closing the terminal (habit from working in remote servers).

Confirmed it was already set to “Analog Stereo Duplex”. I’m still learning the screenshot tool so wasn’t able to get a screen with all of the options listed.

I haven’t edited anything to turn off autospawn for pulse that I know of. At least in /etc/pulse/client.conf the line “autospawn = yes” is present. These are the commands I used to kill pulse a couple sessions ago. I’ve since rebooted a couple of times so am not sure if they’re still affecting things:
systemctl --user stop pulseaudio.socket
systemctl --user stop pulseaudio.service
I ran the command you suggested and now ~/.asoundrc has the two lines setting the default soundcard to 1. Let me go ahead and restart the computer and see what happens.
@mikobuntu Okay so this was interesting!
After re-booting, all of the sound on my system stopped working entirely. Not just Reaper/Renoise, but also playing normal audio files with Celluloid. It’s the same as my issue with Renoise where sound appears to play (no errors) but no sound comes out of the speakers.
I emptied out ~/.asoundrc and restarted and everything came back, though Renoise has the same problem. Is Renoise for some reason doing something similar with the pcm defaults?
And noted on running from a live USB drive. I will give it a shot but it will take a little while as I don’t get much free time.
Side question that hopefully isn’t too involved: do you know a good jack tutorial anywhere? As I have time I’m also trying to get Jack to work with Reaper but getting nowhere. I don’t think it’s the same issue, just me not knowing Jack very well.
ok cool :-
(1) Looks perfect
(2) That should be fine, I was expecting it to be duplex.
[ yeah it’s a bit tricky to get a screenshot with a drop down menu as losing mouse focus will close it ]
ways around this are, use a screenshot tool with a countdown timer, or use peek and record an animated .gif .
(3) looks good ! and I was concerned that you had maybe masked a systemctl setting, but again all looks good.
For the asoundrc file, I will maybe have to specify a few extra options as this should work ( I will get to this in my next post for you ) This at least shows me that we can override your system alsa settings from here, which is much easier that editing system files.
Hopefully the live usb method sheds some light on the issue.
I will definitely be able to dig out some info on getting jack up and running for you, I’ll post in a reply soon.
pcm.!default {
type hw
card 1
}ctl.!default {
type hw
card 0
}
@nick Can you please paste this into the ~/.asoundrc file and do the usual procedures, thanks
I was trying to make you a 1 liner to run from the commandline, but it was starting to get complex using echo with newlines and tabs 
If this fails, maybe even try setting the card numbers to 0 or 2 , It will probably fail, but worth a try I guess.
We could maybe look at setting up dmix next, but in the meantime here’s a great source for alsa related stuff Asoundrc - AlsaProject
