[PATCH] ASoC: codecs: jz4725b: Various improvements and fixes
From: Siarhei Volkau
Date: Sat Oct 08 2022 - 14:18:42 EST
The patch fixes:
- incorrectly represented dB values in alsamixer, et al.
- Line In path stays powered off during capturing or
bypass to mixer.
The patch improves:
- Exposes all mixer inputs (both Mics, LineIn and DAC) with their
gain controls.
- 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.
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).
