Hi everyone,
ok, I'm trying to get sound out of my Creative SoundBlaster MP3+ (external,
USB).
So far, all the logs show me that it's being recognized by snd-usb-audio, at
least:
| Code: |

All volume settings were demuted and set to max using alsamixer or kmix.
Now when I try to play something in xmms or bmp, the time label gets frozen,
and I don't hear anything (the GUI doesn't freeze, though).
Instead, this is what i get in a console:
| Code: | | ** WARNING **: alsa_free(): snd_pcm_start() failed: Broken pipe |
This message is outputted infinitely until I kill -9 the player.
Meanwhile, the same happens in the kernel log, the message
| Code: | | cannot submit datapipe for urb 0, err = -38 |
is also being outputted infinitely.
I've already tried using mmap mode and/or software mixing and playing with
aplay or mplayer.
Nothing helps.
Any ideas?
Thanks,
Artjom |
