Yes I did try model=acer-aspire-4930g. That gives me even lesser functionality than model=auto (Surround volume can no longer be used to adjust line-out volume) I think the 4930G uses a ALC888 and the 6935/6920/8920/8930 use a ALC889 (0x10ec0889) codec. Any way of obtaining the verbs from the Windows driver?
Some more info (obtained by generally trying out verbs)
0x15 SET_EAPD_BTLENABLE 2 and 0x14 SET_EAPD_BTLENABLE 2 are both needed to get the amps fired
0x14 SET_CONNECT_SEL 0x00 connects the laptop speakers and disconnects line-out 0x14 SET_CONNECT_SEL 0x01 connects the line-out but laptop speakers continue to function
0x15 SET_CONNECT_SEL 0x00 connects the laptop speakers and disconnects the subwoofer 0x14 SET_CONNECT_SEL 0x01 connects the subwoofer but laptop speakers continue to function 0x15 SET_PIN_WIDGET_CONTROL 0x00 turns off the line-out 0x15 SET_PIN_WIDGET_CONTROL 0x40 turns on the line-out but laptop-speakers stay on 0x15 SET_PIN_WIDGET_CONTROL 0xc0 Same as above but line-out volume is much higher
0x0c SET_AMP_GAIN_MUTE 0x7080 (Mutes all channels) 0x0c SET_AMP_GAIN_MUTE 0x7000 (Un-mutes all channels)
The Realtek Linux driver had one ALC889 model entry for the M90V ALC889 codec with model param as asus-dig. I tried that out. With that headphone jack sensing worked in the sense that as soon as a headphone was plugged in, the subwoofer turned off, though the front speakers were still on. I did get line-out volume though, it was very feeble. The internal mic still did not work and nor did an external one.

I seem to have the same card looking at lspci -v, and I experience the same problems. My laptop is an Acer Aspire 6930, so maybe the Acer bioses are broken? I got the sound to work (with the controls mapped uncorrectly), but I still can't make the mic work. I'll try with that model, I also tried with acer and acer-aspire with no luck.

Hi, Even after enabling DEBUG using --with-debug option with

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.
OK, this implies that the BIOS setup is broken. Did you try model=acer-aspire-4930g, BTW?
Takashi
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.
