Cannot access sound card

[Jonathan Lange]

When running recordmydesktop:

$ recordmydesktop
Initial recording window is set to:
X:0 Y:0 Width:1280 Height:800
Adjusted recording window is set to:
X:0 Y:0 Width:1280 Height:800
Your window manager appears to be Compiz

Detected compositing window manager.
Reverting to full screen capture at every frame.
To disable this check run with --no-wm-check
(though that is not advised, since it will probably produce faulty results).

I get the exact same error running fully-updated Oneiric. I also get a similar error when running ffmpeg:

It would seem something has broken in alsa land.

[Martin Nordholts (enselic)]

This bug report is now almost 10 years old, and as far I know this issue was sorted out several years ago. It works for me now at least.

If this can still be reproduced, please reopen with an updated step-by-step on how to reproduce.
