Subject: [PATCH 1268/1295] ASoC: DACplusADCPro - fix 16bit sample support in
|
|
clock consumer mode
|
|
|
|
The former code did not adjust the physical sample width when in
|
|
clock consumer mode and has taken the fixed 32 bit default. This
|
|
has caused the audio to be played at half its frequency due to
|
|
the fixed bclk_ratio of 64.
|
|
|
|
Problem appears only on PI5 as on the former PIs the I2S module
|
|
did simply run at fixed 64x rate.
