The error ir reported because two subsequent readings from a register return the same value. Maybe the assumption that subsequent reads from that specific register should be different is invalid. > This is what cat /dev/sndstat says: >=20 > FreeBSD Audio Driver (newpcm) > Installed devices: > pcm0: <SiS 7012> at io 0xe000, 0xe100 irq 18 bufsz 16384 kld snd_ich > (1p/1r/0v channels duplex default) >=20 > Any suggestions on what I should do or should I install my old soundcard? If you're into shotgun debugging you could try returning the default value immediately from ich_calibrate, and see if it works. :-) If you have another working soundcard, I'd plug that in, and disable the onboard sound in the bios.
