Tried all thinkable settings. * Increasing Microphone levels leads to some strange internal feedback. That means, at some point when the feedback starts, it just starts, but i have no clue what audio source did actually trigger it. * Touching the mixer channel "Smart 5.1" in alsamixer makes alsamicer crash. After quite some days of frustration and the inability to get help i however managed to learn how to build a kernel and how to git bisect. So this is what i did: root@Blackrock ~src/alsa-kernel (git)-[7b315bb...|bisect] # git bisect log git bisect start '--' 'sound/pci' # bad: [81a2f603f94d6da108ddd8e3535294445097f730] ALSA: ac97: replace open- coded, error-prone stuff with AC97 bit defines git bisect bad 81a2f603f94d6da108ddd8e3535294445097f730 # good: [f6f94e2ab1b33f0082ac22d71f66385a60d8157f] Linux 2.6.36 git bisect good f6f94e2ab1b33f0082ac22d71f66385a60d8157f # bad: [28c4edb71d21623f1e47422194d865d2b6712fd4] ALSA: HDA: Rename "Int Mic" to "Internal Mic" git bisect bad 28c4edb71d21623f1e47422194d865d2b6712fd4 # bad: [0e7adbe263f89ea2ef15b5af5e80a812b2a85025] ALSA: hda - Disable sticky PCM stream assignment for AD codecs git bisect bad 0e7adbe263f89ea2ef15b5af5e80a812b2a85025 # bad: [5637edb2e1c2d13b276748508ae17f319fb7f066] ALSA: HDA: Sort CXT5066 quirk table git bisect bad 5637edb2e1c2d13b276748508ae17f319fb7f066 # bad: [18675e4283f575594d55ef1239c14ab5b4de53b6] ALSA: hda - Add fixup for FSC Celsius H270 git bisect bad 18675e4283f575594d55ef1239c14ab5b4de53b6 # good: [eea7dc932bfa802ad0377755ea821f416f4f8623] ALSA: hda - Use new inputs[] field to parse input-pins for STAC/IDT codecs git bisect good eea7dc932bfa802ad0377755ea821f416f4f8623 # bad: [263d0328c46995d8e4fb478005177839104483d2] ALSA: hda - Improve input control names for IDT/STAC codecs git bisect bad 263d0328c46995d8e4fb478005177839104483d2 # bad: [9737731d64bfa64ab4fc04b46ae5b650f6432222] Merge branch 'fix/hda' into topic/hda git bisect bad 9737731d64bfa64ab4fc04b46ae5b650f6432222 # bad: [7b315bb4980448250c80a7464c256b54d546cb26] ALSA: hda - Use new inputs[] field to parse input-pins for VIA codecs git bisect bad 7b315bb4980448250c80a7464c256b54d546cb26 root@Blackrock ~src/alsa-kernel (git)-[7b315bb...|bisect] # git bisect bad 7b315bb4980448250c80a7464c256b54d546cb26 is the first bad commit commit 7b315bb4980448250c80a7464c256b54d546cb26 Author: Takashi Iwai Date: Mon Aug 30 13:06:30 2010 +0200 ALSA: hda - Use new inputs[] field to parse input-pins for VIA codecs Signed-off-by: Takashi Iwai :040000 040000 fb32bef12d78f90f00020cf375fddd36be1cdfbe 02f61291093ce6c7c8e7e1bd98fd87f9338702a1 M sound Oh, and here are debug infos from when i first tried to report the problem: bad: http://www.alsa-project.org/db/?f=0f29e6de98ea9fefae5c6e2adb43ff8f8eede697 good: http://www.alsa-project.org/db/?f=11290fe50066e9bcd6a244f2c83b1c66c9dd201b I hope someone can take it from here. I'm not much more than a user. Just because i managed to build a kernel doesn't mean i can fix this bug. Wolfgang Scheicher
