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

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

This sounds like a bug in cs4265_readable_register(); try replacing CS4265_SPDIF_CTL2 with CS4265_MAX_REGISTER.
