> How do you feel about building Alsa as modules instead of building it into the kernel? When using modules you can blacklist other sound cards (the MB audio stuff for instance) and you get a little more visibility into what's is at least loaded. That way we could, at least as a test, run your setup as a USB only system. If at that point you can record mix audio in something like Audacity and play Audacity and Youtube through the Behringer then, I would think, we would have determined that this is an application issue. |

Well, this is the current state of affairs: |
| 10 |
|
| 11 |
--recording with "arecord -r 48 -fdat test.wav works |
| 12 |
--playback "aplay test.wav" works |
| 13 |
--playing a music file foo.wav with aplay works |
| 14 |
--playing youtube doesn't work |
| 15 |
--playing the same foo.wav file with audacious doesn't work: it |
| 16 |
displays the message "ALSA error: snd_pcm_open failed: No such device" |
| 17 |
(searching for that string in menuconfig returns nothing) |
