Prior to version 7.0, Fedora 22 also suffered this problem seem lost "+" between speaker and LO http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/src/modules/alsa/mixer/paths?id=aec811798cd883a454b9b5cd82c77831906bbd2d state.PCH { control.1 { iface MIXER name 'Speaker LO Playback Volume' value.0 87 value.1 87 comment { access 'read write' type INTEGER count 2 range '0 - 87' dbmin -6525 dbmax 0 dbvalue.0 0 dbvalue.1 0 } Any Update on this? This continues in 4.4-rcX also. https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda?id=e7fdd52779a6c2b49d457f452296a77c8cffef6a Patch implement loopback mkxing control which mute the loopback Mixing of those input pins Does PA need to do any config changes to take this patch into account? Any Update on this? Continues with: 4.5.0-0.rc4.git2.2.fc24.x86_64 / pulseaudio-7.1-1.fc23.x86_64

you can use hint (early patching) to disable analog mixer if the noise come from analog mixer
mixer_nid = 0
- mixer_nid (int): specifies the widget NID of the analog-loopback
mixer
https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/Documentation/sound/alsa/HD-Audio.txt
Setting mixer_nid=0 in grub didn't fix it. I know this laptop has AAMIX on it I wonder if ALC292_FIXUP_DISABLE_AAMIX quirk may fix issue. This laptop also has bad white noise on analog I reported about long time ago. If you still found those mic playback volume control, this mean that you have not disabled aamix by earky patching How do you add the patch file in /etc/modprobe.d/alsa-base.conf Hello I can confirm that with the mixer_nid = 0 hint the problem goes away. Running ubuntu 14.04 with kernel 4.4.0-21-generic and pulseaudio 4.0 Dell Precision M6800 Cheers Whats the patch file look like, still have popping here. I did try passing mixer_nid to driver, didn't work? I got it working [codec] 0x10ec0292 0x102805cd 0 [hint] mixer_nid = 0 Could we perhaps add a quirk in codec driver if this impacts everyone with this vendor/subvendor #? This isn't PulseAudio bug, should be a kernel quirk otherwise. |
