virtio-snd: add more supported sampling rates #184

Closed aditpape closed 1 month ago

aditpape commented 12 months ago

Problem: virtio soundcard does not support sampling rate of 24kHz used for e.g. 'HD voice' or 'super wide band voice call'

Analysis: virtio claims to be inspired from Intel HDA spec - according to that spec the range of possible sampling rates is derived from the two base rates 44100 and 48000 by applying multiplier 1..4 and/or divisor 1..8

--> 24kHz is matching 48kHz divided by 2 and falls into such standardized range.

Dear TC, is there enough information given to initiate a voting or is there anything missing from my end? THX, Regards, Andreas
