Hello,
I'm not sure of the usage for GET_PROC_COEF/GET_COEF_INDEX, and found
that their return value is unstable (changing all the time) for codec:
Codec: Realtek ALC888
Address: 2
Function Id: 0x1
Vendor Id: 0x10ec0888
Subsystem Id: 0x80860023
Revision Id: 0x100202
For example:
# hda-verb /dev/snd/hwC0D2 0x20 GET_PROC_COEF 0
nid = 0x20, verb = 0xc00, param = 0x0
value = 0x80
# hda-verb /dev/snd/hwC0D2 0x20 GET_COEF_INDEX 0
nid = 0x20, verb = 0xd00, param = 0x0
value = 0xe
# hda-verb /dev/snd/hwC0D2 0x20 GET_PROC_COEF 0
nid = 0x20, verb = 0xc00, param = 0x0
value = 0x9c00
# hda-verb /dev/snd/hwC0D2 0x20 GET_COEF_INDEX 0
nid = 0x20, verb = 0xd00, param = 0x0
value = 0xf
I wonder if this is the normal case?
Thanks,
Fengguang
