[Sound-open-firmware] automated audio testing

Hi,

I'm bisecting a playback breakage on Up^2 and within just 122 commits I've allso found a second breakage, which however then has been fixed. My question is: how difficult would it be to implement an automated audio quality testing CI? Like real audio playback of an audio sample to an analog or a digital output with a subsequent capture and comparison? Potentially also with a similar capture test? I think it would be of a great help.

Thanks Guennadi
