[alsa-devel] ALSA-SOC support for OpenRD Client/Ultimate

[Robas, Teodor]

Solved. All functions I tried (playback, volume control, muting) work fine.

The codec is found as:
cs42l51-codec 0-004a: found device cs42l51 rev 1

Manny thanks for this driver.

Also thanks to Mark Brown for pointing the info in the right direction.
