Hello everyone,
I compiled today the Kernel 3.4.0-rc7 from the git and used this git to add the FTU support: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git
Unfortunately, all my USB sound card simply stopped working.
The FTU doesn't produce any sound, nor through Alsa or Jack. I tried playing a simple song through mplayer and nothing. I double checked the mixer, all volumes are set as they should. I checked dmesg, no error that could help. I'm running Ubuntu, and the only thing I can hear is the welcoming sound of ubuntu being cut-off almost instantly.
I tested my Edirol UA-25Ex, it is working all ok.
Correction, the UA-25Ex doesn't work either. The sound dies out after a few minutes being used.
When the sound dies out, dmesg prints:
[ 550.114621] urb status -32 [ 551.601237] urb status -32 [ 551.681206] urb status -32 [ 553.563336] urb status -32 [ 565.588044] urb status -32 [ 566.786965] urb status -32 [ 625.130221] cannot submit urb 0, error -28: not enough bandwidth
If there is any other info I can provide, let me know,
Aurélien
