Error opening PCM device Device or resource busy
Hope I haven't missed an answer; did many searches over several days but could not find a duplicate problem or a solution to a related problem that worked. Tried lsof /dev/snd/{whatever your device name is} but after trying different possibilities would see "No such file or directory".
I realize there could be many causes, so thanks in advance for any suggsetions. System: Mint 5.0 via Ubuntu 8.04 (Hardy), GNOME 2.22.3, 2GB memory, AMD Athlon 64 3200+ Every time the sound stops, there is a syslog entry that says: Code:
Aug 22 12:05:28 forest pulseaudio[6421]: module-alsa-sink.c: Error opening PCM device front:0: Device or resource busy Code:
tmr@forest ~ $ lspci Code:
Aug 22 15:02:58 forest pulseaudio[6447]: alsa-util.c: Device front:0 doesn't support 44100 Hz, changed to 48000 Hz. |
Do you have /dev/snd directory in your system? What devices have you tried with lsof, and when does the "File not found" error occurs?
In my system I have ls /dev/snd controlC0 hwC0D3 pcmC0D0c pcmC0D0p seq timer with 2 pcm devices as you can see. |
