[alsa-devel] [RFC][PATCH 00/13] bebob: a new driver for BridgeCo BeBoB based device

[Takashi Sakamoto]

Hi Daniel,

Thanks for your testing.

At first, I describe our system to test. I use Ubuntu 13.10. You use 
Fedora 19.

1.pulseaudio
PulseAudio can automatically load 'module-alsa-card' with 
'module-udev-detect' (utilizing sysfs/dbus). But for snd-bebob, this 
mecanism doesn't work because PulseAudio cannot decide profiles for the 
card even if success to detect.

For this problem, I have a need to commit some codes for PulseAudio but 
this may be my future work.

Well, when I test with PulseAudio, I always directly load 
'module-alsa-sink' or 'module-alsa-source' by these lines:
$ pactl load-module module-alsa-sink device=hw:X,X
$ pactl load-module module-alsa-source device=hw:X,X

See in detail:

2.dmesg
Hm. I want to know which asynchronous transaction is failed.
[  446.796563] snd-bebob fw1.0: transaction failed: no ack
[  446.838567] snd-bebob fw1.0: transaction failed: no ack

Would you investigate which transactions cannot get 'no ack'?


Thank you
