Bug Description

[SRU Justification]

[Impact]
Internal speaker is distorted after suspend for 30 seconds on Intel platforms with Cirrus CS42L43 audio codec

[Fix]
Fixed by the https://<email address hidden>/ from cirrus and got ACK from upstream.

[Test Case]
1. Power on the machine with the Cirrus audio codec CS42L43
2. Play sound with internal speaker
3. Suspend the machine for 30 seconds
4. Check the sound output by play sound by internal speaker again

[Where problems could occur]
Only affect the machines with particular Cirrus audio codec. The risk is restricted.

This bug is awaiting verification that the linux-oem-6.11/6.11.0-1007.7 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done-noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed-noble-linux-oem-6.11'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
