Hello, Forwarding my regression bug report submission per the instructions in "Reporting regressions". #regzbot introduced: 5aec989130 https://bugzilla.kernel.org/show_bug.cgi?id=217440 Regards, Joseph C. Sible ---------- Forwarded message --------- From: <bugzilla-daemon@xxxxxxxxxx> Date: Sat, May 13, 2023 at 3:46 PM Subject: [Bug 217440] New: ALC236 audio disappears from HP 15z-fc000 on warm boot To: <josephcsible@xxxxxxxxx> https://bugzilla.kernel.org/show_bug.cgi?id=217440 Bug ID: 217440 Summary: ALC236 audio disappears from HP 15z-fc000 on warm boot Product: Drivers Version: 2.5 Kernel Version: 6.3.2 Hardware: All OS: Linux Status: NEW Severity: normal Priority: P3 Component: Sound(ALSA) Assignee: perex@xxxxxxxx Reporter: josephcsible@xxxxxxxxx Regression: Yes Bisected 5aec98913095ed3b4424ed6c5fdeb6964e9734da commit-id: On an HP 15z-fc000 laptop that uses Realtek ALC236 for sound, once the system is warm booted ("reboot" from within Linux), sound stops working completely and the device doesn't even show up anymore. Once this happens, the only way to get it to come back is to cold boot ("poweroff" from within Linux, wait for it to turn completely off, and turn it back on with the physical power button). In particular, once you boot from a "bad" kernel, no number of warm boots with "good" kernels will ever bring sound back. I bisected this to commit 5aec989, which first appeared in 5.15-rc6. In addition, I confirmed by doing a custom build of 6.3.2 with reverts of both f30741c (just to avoid a conflict) and 5aec989, which works correctly for me. -- You may reply to this email to add a comment.
