Audacity not recording in Ubuntu Studio

Is there anything I can do to get Audacity to record again in Ubuntu Studio?

I have been using an M-audio 1010LT soundcard with Audacity since Ubuntu Studio 12.04. Recently on Ubuntu Studio 15.04 / Audacity 2.0.6, the cursor got stuck on 0 seconds, was blinking, and not recording. First I tried increasing the latency, (didn’t help) then I unchecked overdub (didn’t work). Software playthrough was already unchecked, so I tried it checked and then put it back since it didn’t make a difference. As a last resort, I removed Audacity and reinstalled it, but to no avail. Finally, I bit the bullet and reinstalled the OS, but no dice.

Overview:

  1. Increased latency
  2. Unchecked overdub
  3. Checked then unchecked software playthrough
  4. Reinstalled Audacity
  5. Reinstalled Ubuntu Studio 15.04

I then played with the latency settings some more just for kicks, but nothing. Thanks for any suggestions for step #6.

First, reset the Audacity Preferences back to defaults by deleting “audacity.cfg” ( ~/.audacity-data/audacity.cfg)
Then ensure that your M-audio 1010LT is operating correctly.
Then reboot.
Then launch Audacity and click on “Help > Audio Device Info”.
Copy and paste the output into your reply.

Thanks for the help. Audacity version is 2.0.6. Audio Device Info is pasted below.

That all looks OK.
Set Audacity to record, then open “PulseAudio Volume Control” (if it’s not installed, install “pavucontrol”) and in the Recording tab, select the input that you want to record from.

Do I need to change the latency correction settings? I tried recording and got this error message:

Latency Correction setting has caused the recorded audio to be hidden before zero.
Audacity has brought it back to start at zero.
You may have to use the Time Shift Tool (<—> or F5) to drag the track to the right place.

Thank for all the help.

The recording is stalling. What input are you trying to record from in pavucontrol?

Are you choosing the “pulse” input in Device Toolbar?

Interface host has a choice of ALSA and OSS, and is set to ALSA
When playback and recording device are set to default, sysdefault, M-Audio 1010LT ICE 1712, spdif, or pulse the recording bar sits at zero and doesn’t move.

I also went into my bios and turned off my internal audio card just in case it was interfering with the M-Audio 1010lt PCI card.

Thanks for all the help.

At Edit > Preferences… then “Recording”, did you try increasing “Audio to buffer”? You said you changed “latency” but “Latency Correction” does not help you start recording, it just time shifts overdub recordings once completed.

How many tracks are you trying to record? Does one track record with Audacity set to one recording channel?

I looked through all the suggestions and someone mentioned making sure the M audio 1010lt sound card was working.

The computer was detecting the PCI sound card, but I opened up the box anyway to see if it was loose. Turns out it was covered with dust from the fan of my new AGP video card. I moved the sound card over one slot and cleaned out all the dust from the box.

After reinstalling everything, the card works fine. I’m guessing the dust was causing some sort of short circuit. Thanks for all the help.
