http://bugzilla.opensuse.org/show_bug.cgi?id=982998 Bug ID: 982998 Summary: PCH sound trashed after update to 4.6.0 Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE 42.1 Status: NEW Severity: Normal Priority: P5 - None Component: Sound Assignee: tiwai@suse.com Reporter: matthew.evans1992@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.79 Safari/537.36 Build Identifier: PCH sound card is no longer detected (in either section of a dual boot!?!) after kernel upgrade to 4.6.0-1.1. The problem persists after booting to 4.5.2. dmesg reports the following: [ 13.540929] snd_hda_intel 0000:00:03.0: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 13.543939] snd_hda_intel 0000:00:1b.0: no codecs found! and the sound card is not listed under aplay -l, or asound/cards, as evidenced by the alsainfo output found here: http://www.alsa-project.org/db/?f=63831b67a3a31fbf9ec7f2c2a55f671f6fd216ea On an identical machine with working sound, these are the detected cards: $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: PCH [HDA Intel PCH], device 0: ALC292 Analog [ALC292 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 So the ALC292 PCH card is no longer being detected by ALSA in my system, though it appears with lspci. Reproducible: Always Actual Results: Only HDMI sound is detected, with no other devices listed by pavucontrol. Expected Results: Both sound cards should be detected and were so before this kernel update. This forum post outlines what I have tried so far, namely fiddling with /etc/modprobe.d/50-sound.conf: https://forums.opensuse.org/showthread.php/518164-PCH-sound-card-trashed-aft... -- You are receiving this mail because: You are on the CC list for the bug.
