Bug Description

[Impact]
Audio device is not available, instead it shows dummy output in the settings

[Fix]
SOF driver looks for a config which both sample width and valid bits are both 32 bits. However, the config in NHLT table is 32-bit sample width and 24-bit valid bits. Should ignore the valid bits in NHLT when the sample width is 32 bits.

Confirmed the below commit in v6.7-rc4 fix the issue
7b4c93a50a2e ALSA: hda: intel-nhlt: Ignore vbps when looking for DMIC 32 bps format

[Test case]
1. check audio input/output on the system
2. System can play and record audio normally

[Where problems could occur]
When the samples assumed to be vbps=32 then the 'noise' introduced by the lower two bits (channel number) have no real life implication on audio quality.

This bug is awaiting verification that the linux-oem-6.5/6.5.0-1013.14 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-jammy-linux-oem-6.5' to 'verification-done-jammy-linux-oem-6.5'. If the problem still exists, change the tag 'verification-needed-jammy-linux-oem-6.5' to 'verification-failed-jammy-linux-oem-6.5'.

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!
