probe_mask=8 causes no soundcards. probe_mask=1 works apparently the same as no probe_mask at all. However, it seems that the bug has been fixed elsewhere as I am no longer seeing mute toggling at all (card does not get muted when inactive) but I'll give it some more testing before closing this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1042546 Title: Sound card is muted or mute being constantly toggled when no audio is played To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1042546/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Constant mute toggling is back. I am not exactly sure why it was working properly for a short while but the bug is certainly not fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1042546 Title: Sound card is muted or mute being constantly toggled when no audio is played To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1042546/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Raymond, thans for your help with debugging audio issues. This text is relevant to this bug: Codec-Probing Problem ~ A less often but a more severe problem is the codec probing. When BIOS reports the available codec slots wrongly, the driver gets confused and tries to access the non-existing codec slot. This often results in the total screw-up, and destructs the further communication with the codec chips. The symptom appears usually as error messages like: hda_intel: azx_get_response timeout, switching to polling mode: last cmd=0x12345678 hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x12345678 The first line is a warning, and this is usually relatively harmless. It means that the codec response isn't notified via an IRQ. The driver uses explicit polling method to read the response. It gives very slight CPU overhead, but you'd unlikely notice it. The second line is, however, a fatal error. If this happens, usually it means that something is really wrong. Most likely you are accessing a non-existing codec slot. Thus, if the second error message appears, try to narrow the probed codec slots via `probe_mask` option. It's a bitmask, and each bit corresponds to the codec slot. For example, to probe only the first slot, pass `probe_mask=1`. For the first and the third slots, pass `probe_mask=5` (where 5 = 1 | 4), and so on. Since 2.6.29 kernel, the driver has a more robust probing method, so this error might happen rarely, though. On a machine with a broken BIOS, sometimes you need to force the driver to probe the codec slots the hardware doesn't report for use. In such a case, turn the bit 8 (0x100) of `probe_mask` option on. Then the rest 8 bits are passed as the codec slots to probe unconditionally. For example, `probe_mask=0x103` will force to probe the codec slots 0 and 1 no matter what the hardware reports. http://git.alsa-project.org/?p=alsa- kernel.git;a=blob_plain;f=Documentation/sound/alsa/HD-Audio.txt;hb=HEAD -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1042546 Title: Sound card is muted or mute being constantly toggled when no audio is played To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1042546/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
