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.
