[alsa-devel] cs4265 : alsactl store and "C data buffer" fails

[Matt Flax]

Hi,

When alsactl store is run with a cs4265 chip, the following error occurs 
(from https://github.com/Audio-Injector/Ultra/issues/25) :

$ sudo alsactl store
alsactl: get_control:256: Cannot read control '2,0,0,C Data Buffer,0': 
Input/output error


Upon commenting out the C data buffer control it works :

Can you suggest a suitable method for fixing this bug ?


thanks

Matt
