The patchset fixes: - Line In path stays powered off during capturing or bypass to mixer. - incorrectly represented dB values in alsamixer, et al. - incorrect represented Capture input selector in alsamixer in Playback tab. - wrong control selected as Capture Master
The patchset improves: - Exposes output stage (post mixer) gain control and makes it new Master playback gain, DAC gain was the previous master. However, no Master mute now. - Exposes all mixer inputs (both Mics, LineIn and DAC) with their gain controls.
Known issues: - Bypass path enablement isn't applied immediately, for make things going bit clock needs to be triggered for a bit, e.g. by aplay dummy.wav It might be a hardware bug, since the bit clock isn't declared as required for codec operation.
Tested on: - Ritmix RZX-27 (jz4725b). - Ritmix RZX-50 (jz4755).
Diff from v1: - each change in a separate patch
