Subject: [PATCH] audio: ensure effect chain with specific session id is unique
|
|
|
|
It's possible that tracks with the same session id running on various
|
|
playback outputs, which causes effect chain being created on the same
|
|
session twice. As a result, the same effect engine will be released
|
|
twice as the same context is reused.
|
|
|
|
Output that has effect chain with same session id is more preferable.
|
|
|
|
Test: No regression with Play Music and Effects
