This is really frustrating. I spent 2 hours last night trying to get my line-ins working to no avail. I have verified on my windows install that the audio source is connected correctly because it works there.
I have installed “Envy24 control Utility 0.6.0” which can monitor the inputs/outputs of the M-audio card and change settings and such. I have made sure I un-muted the input tracks in it.
Here are the things I have done to troubleshoot:
*I have gone into Ubuntu’s sound preferences and changed the “sound capture” and “default mixer tracks” to every single option in the list. (Thinking that maybe it had to be a certain one in order for line-in to work).
*I have gone into the “system tray’s” volume control and fiddled with the settings on every single device listed, making sure that none of the microphone icons had a little red X over them, making sure levels are up… etc. I read on some forum thread that you had to make sure there was a little box checked that said “capture”, but from what I gather that is for older ubuntu builds as 9.04 one doesn’t have anything like that, and instead says “capture” at the top when you select the device.
*I have disabled my motherboard’s onboard sound via the BIOS. Even still, Ubuntu had drivers installed for it. I thought they might be interfering so I even blacklisted them. Didn’t work
*I read a lot of stuff saying Pulseaudio causes a lot of problems. So I uninstalled it completely (also while my onboard sound was blacklisted)
None of this stuff helped. Still getting no levels on the mixer, nothing coming into Audacity.
Think I’m going to have to settle for my onboard line in for the moment, until I can get this fixed. Assuming I can even get it to work either.
Any input/help is appreciated.
