Monitor Speaker sound after issue happened
Sorry for my mistake. The chipset PCH should be LynxPoint Q87. PulseAudio doesn't seem to be involved in your test, so it looks like you filed the bug in the wrong place. (In reply to Tanu Kaskinen from comment #5) > PulseAudio doesn't seem to be involved in your test, so it looks like you > filed the bug in the wrong place. Thanks Tanu! I changed product to DRI. I used the same method to test on BSW, issue doesn't happen. Bug scrub: Hi Focus, Could check this bug and discuss with Mengdong Can the bug be closed? Sure, thanks for your great help! fixed. Confirmed with Kenny. So closed |
