Hey folks, Entirely unrelated to the regression on this board that we dealt with the other week, I have (and have had for a bit), a problem with audio on this laptop. After a while of use, I'll have a problem like this: Sep 12 20:59:30 oliver kernel: haswell-pcm-audio haswell-pcm-audio: FW loaded, mailbox readback FW info: type 01, - version: 00.00, build 77, source commit id: 876ac6906f31a43b6772b23c7c983ce9dcb18a19 (everything is fine, audio works, is in use) Sep 12 21:24:04 oliver kernel: haswell-pcm-audio haswell-pcm-audio: error: audio DSP boot timeout IPCD 0x0 IPCX 0x0 Sep 12 21:24:04 oliver kernel: haswell-pcm-audio haswell-pcm-audio: ipc: --message timeout-- ipcx 0x83000000 isr 0x00000000 ipcd 0x00000000 imrx 0x7fff0000 Sep 12 21:24:04 oliver kernel: haswell-pcm-audio haswell-pcm-audio: error: stream commit failed Sep 12 21:24:04 oliver kernel: System PCM: error: failed to commit stream -110 Sep 12 21:24:04 oliver kernel: haswell-pcm-audio haswell-pcm-audio: ASoC: haswell-pcm-audio hw params failed: -110 Sep 12 21:24:04 oliver kernel: System PCM: ASoC: hw_params FE failed -110 With those last 4 messages repeating constantly (~3 sets per second, and the above are from v4.13, but I've had similar for as long as the driver has been mainline I think) and it only stops when I reboot. Rebooting may or may not clear the problem, last night I had to power off to get audio to come back up. I'm not quite sure where to begin debugging this issue. Does anyone have any suggestions? Thanks! -- Tom
