i found out that using the following command suppresses the noise for a few
seconds, then it continues:
$ cat /proc/asound/card*/codec* | grep "Vendor Id"
Vendor Id: 0x10ec0257
Vendor Id: 0x8086281c
is there any suggestions what might be the real cause of noise?
i don't have much experience doing kernel development, so I would
appreciate it if someone guided me in the correct direction to fix this
