Hi, Even after enabling DEBUG using --with-debug option with configure when compiling the alsa-driver snapshot leaves no more error messages in the dmesg logs. The only message relating to HDA is: [ 41.104817] hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj. I just got the line-out output to work by toggling the surround volume. I still think it's a mapping problem. The headphone switch is turning the subwoofer on and off, and the surround volume is controlling the line-out volume. None of the line-in devices function and all of the amp-ins 0x0b to 0x0f are muted. Cannot find any verb to unmute them. hda-verb with SET_EAPD_BTLENABLE 2 at 0x15 is still needed at startup to fire up the amps. Please help.
