Description Jordan Maris 2017-01-24 12:46:43 UTC

On linux-4.5.0-1 upwards, byt_max98080 sound cards (in some bay trail devices) no longer seem to initialise.

After updating, the card dissapears from dmesg and alsa, and gives out no sound.

Reverting to a version of the kernel prior to linux-4.5.0-1 resolves this issue.

There has been further discussion of the subject on the ArchLinux bugtracker, however so far no bug has been registered on the kernel bugtracker.

The thread on the Arch bugtracker is here : https://bugs.archlinux.org/task/48936

I'm sorry if this report lacks detail or important information, It's the first time I have posted a bug here. Please do not hesitate to ask me for any further information.

Thank you all in advance for your time and effort
