Is this a regression from the old kernel?
I think it's a regression, but not sure. I've downgraded kernel to 2.6.25.8, testing now. First I have capture problems,after that I see dmesg messages. This problem appears randomly, after reboot capture is ok.
Seems problem exist for 2.6.35.8 too (25 was typo :)) capture randomly stops, but without dmesg messages.
steps to reproduce: i have open audio player (amarok) and open and close mumble or audacity :). after some steps (opening-closing apps with audio capturing) capture is down.
Does the problem still happen with 3.12 kernel?
I've forgotten about this bug :) Now I have another (intel-based) laptop and here seems this bug not appears (at least with 3.12). I can test later my old laptop ( ~1.5 weeks later ).
OK, if it's still a problem, please give alsa-info.sh output. Run it with --no-upload option, and attach the output to bugzilla.
Sorry for the late answer, I've tested my old laptop recently with 3.12.6 kernel and I couldn't reproduce this bug. I think the bug can be closed :)
