Subject: add DSD for ThinkBook 16p G4 IRH with Subsystem Id of :

Sorry for missing the info within patch and not familiar with the
mailing system using git. As mentioned in the subject,
the patch is using to fix the sound issue of ThinkBook 16p G4 IRH with
Subsystem Id of : 0x17aa38a9. But this just enable the downside (bass)
speakers. When I tried to adjust the volumn, it atually mapped to the
frequency division (the lower volumn actually set the bass speakers,
and higher volumn map to the louder sound of up facing speakers).
Wondering if this related to ALSA?
