Sound not working with 4.4 #80

From dmesg:

[    4.416443] haswell-pcm-audio haswell-pcm-audio: error: DMA request channel failed
[    4.416473] haswell-pcm-audio haswell-pcm-audio: error: failed to load firmware

same issue here.

steviedons commented 8 years ago

Yep, just upgraded to the 4.4 kernel and got exactly the same error in dmesg.

raphael commented 8 years ago

I think it has to do with:

sst-acpi INT3438:00: DesignWare DMA Controller, 0 channels

This should say 8 channels and not 0.

Fixed the sound in release 4.4-3.

steviedons commented 8 years ago

Just updated to 4.4-3 and sound is fine, thank you for the quick updates.

roobyz commented 8 years ago

it's better than fine... this totally fixed the issue I had where the volume always seemed to be a bit low all the time. Many thanks for the excellent work.

@raphael how can I buy you a beer?

raphael commented 8 years ago

Since you ask: it'd be cool to have a PPA for this kernel. I am not using Debian or Ubuntu so it's hard for me to provide one (I tried). If there was one I'd be able to remove the binaries from this repo which would make it a lot easier to maintain...
