Bug description:
[Impact]
When the speaker volume is at 100%, noise is present during audio playback.
[Fix]
Realtek provides a patch to fix this issue, which will be included in 6.16.
https://patchwork.kernel.org/project/alsa-devel/patch/20250602085851.4081886-1-shumi...@realtek.com/
[Test]
1. Install Ubuntu 24.04 on the machine with rt1320 asoc and boot to OS
2. Adjust the speaker volume to high
3. Enter Sound settings ->Output and click on test button
4. Click on Frotn Left speaker to perform playback test
5. There should be no noise during audio test
[Where problems could occur]
It changes the rt1320 asoc registers value, so it only affects the machines
with rt1320 asoc codec. We have verified the patch didn't lead to any
regression, so it should be pretty safe to include it.
