Subject: [PATCH] rpi sound cards: Fix Codec Zero rate switching
|
|
|
|
The Raspberry Pi Codec Zero (and IQaudIO Codec) don't notify the DA7213
|
|
codec when it needs to change PLL frequencies. As a result, audio can
|
|
be played at the wrong rate - play a 48kHz sound immediately after a
|
|
44.1kHz sound to see the effect, but in some configurations the codec
|
|
can lock into the wrong state and always get some rates wrong.
|
|
|
|
Add the necessary notification to fix the issue.
