https://bugzilla.suse.com/show_bug.cgi?id=1226449 Bug ID: 1226449 Summary: Intermittent sound Lenovo Legion Pro 7 16ARX8H Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Sound Assignee: tiwai@suse.com Reporter: brynn@hotmail.co.uk QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Created attachment 875531 --> https://bugzilla.suse.com/attachment.cgi?id=875531&action=edit alsa -info.sh With no sound I have intermittent sound from my speakers. Ive had this on a couple of forums for a while to try gather more info but no luck. The quirks have only recently been added to allow the speakers to work and they do but they stop after a few minutes if i open another window or click a notification. However, if i open a video in vlc before they have stopped it will play fine for half an hour. When they have stopped I can bring it back by setting my laptop to sleep and waking it up again the immediately playing something They have stopped in the time its taken to type this out. I’ve attached alsa-info.sh with the sound working and one without from the same boot a few minutes apart. To work around this i can play a long audio file on loop with the volume set to 0. This is somewhat related to Bug 1223462. I never noticed this being an issue with 6.7.9-1-default but don't have it any more and its too far back in the repo history for me to download.

Is it only about the speaker output? That is, does the headphone output suffer from the same problem, or does it keep working? -- You are receiving this mail because: You are on the CC list for the bug.

Check the content of /sys/module/snd_hda_intel/parameters/power_save whether it's kept 0. Some system daemon (like power tuning stuff) may turn this on/off automatically, too. Note that, if even the above helps, it's merely a workaround. But it'd good to know if this prevents the issue. -- You are receiving this mail because: You are on the CC list for the bug.

As I have read on the forums this hasn't had an effect since the release of Leap 15.5. I'm not sure how much relevance that has to Tumbleweed though. Editing the value in /sys/module/snd_hda_intel/parameters/power_save with "echo 0 > /sys/module/snd_hda_intel/parameters/power_save" as root works and it mostly stayed but on one occasion reverted and i'm not sure what was different to cause this. However one of the legion/linux forums has suggested changing /sys/module/snd_hda_intel/parameters/power_save_controller to 'N' as well. So the last couple of weeks I have a script that changes these values at boot and everything appears to be fine. From what I've been reading this effects several distros. Thank you for your time and help. -- You are receiving this mail because: You are on the CC list for the bug.

This is with power_save set as 0 and power_save_controller set to N It is still much much better than it was -- You are receiving this mail because: You are on the CC list for the bug.

Could you check the value in /sys/modules/snd_hda_intel/parameters/power_save and whether it's still 0 or not if the problem appears? If it's non-zero, then it's likely the service changing power_save parameter triggered the problem again. If it's kept 0 but the bug appears, it means that the original problem can be somewhere else. -- You are receiving this mail because: You are on the CC list for the bug.

Once after the build finishes, it'll appear at http://download.opensuse.org/repositories/home:/tiwai:/bsc1226449/standard/ Please install the kernel from there later, and boot with snd_hda_intel.pm_blacklist=2 boot parameter. This should keep the runtime PM disabled no matter which power_save option is set. -- You are receiving this mail because: You are on the CC list for the bug.
