Tested on kernel 5.15 on Razer Blade 14 (2021)

Description:
On my Razer Blade 14(2021), the headphone jack does not properly. It only produces a muffled (only high frequencies), low volume and apparently mono output.[1]
The audio codec is ALC 897

Additional info:
I tried to sniff the verbs from the Windows driver and re-apply the verb with nid=0x20
to my device[2][3], which does not work and causes the headphone jack to produce no sound at all. The verbs are attached.
