Set PC Beeper rounting to HDA by command line with coefficient registers
by TomasFilip from LinuxQuestions.org on (#58AYX)
Hello all,
I'm trying to configure HDA Realtek ALC888 and ALC262 codec to redirect standard PC Beeper to Line Out/HP out signal. The best will by command line (or C program) to setup for HDA codec. Speaker signals on buzzer is working well but not throught HDA.
I understant hint is described by PC Beep Hidden Register. I'm found it here
https://www.kernel.org/doc/html/late...k-pc-beep.html
From datasheet, of ALC262 looks that registers are plus minus correct.
page 34. http://realtek.info/pdf/alc262.pdf
Is there any way how to read or just write processing coefficient 0x36 on NID 20h, with proper value from command line?
I'm not sure, looks that /sys/class/sound/hwC0D0/user_pin_configs can be way how to access it, but I don't how to connect coefficients index/registers with that command.
Short example will be very helpfull or any way how to do it
