Hi,
Lately I've been working on fixing various issues people are having with baytrail / cherrytrail devices. One thing I noticed when moving my testing / development to 4.11 is that pulseaudio does not work (it aborts while starting) this seemed to be caused by the new snd_hdmi_lpe_audio module. If I blacklist that all is fine. Any idea what is causing this ?
I noticed it once, too, but I had no time to check further. More interestingly, PA works fine when LPE audio is the single driver (i.e. blacklist Intel SST instead), too. So it's more likely a bug in PA.
What happens when you modprobe LPE audio driver after starting the session? If it kills PA, we can debug more easily :)
I've seen this as well, I could get either one of the two but not both, could this be due to the fact that one set of mixers is configured with UCM and the other driver isn't configured by UCM?
No idea, and I had still no time to check (still processing the pile of pending mails and other bugs :). Let me add PA guys to Cc.
Not sure if anyone here has the hardware and I haven't seen any complaints either -- having a backtrace (or even location of the assert) would be a good start.
Cheers, Arun
