Hrm... Where can I reach that configuration?
BTW, I made some progress. In the dmesg output (attached with the post)
I spotted below lines.
[ 7.948049] hda_codec: ALC269: BIOS auto-probing.
[ 7.948757] input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input9
[ 7.951086] HDA Intel 0000:01:00.1: PCI INT B -> GSI 17 (level, low) -> IRQ 17
[ 7.951126] HDA Intel 0000:01:00.1: setting latency timer to 64
And by looking at Documentation/sound/alsa/HD-Audio-Models.txt for
ALC269, I tried loading sound modules with "model" option set to one of
"basic", "quanta", "eeepc-p703", "eeepc-p901", "fujitsu", "lifebook"
values. Here are my observations: "basic", "lifebook", and "quanta"
managed to get that "ssshhh" noise from the speakers. I can hear the
sound of my fingers typing from the speakers. When I talk to the mic, I
can also hear my own voice. But arecord still doesn't record anything.
Among those working three combinations, "basic" and "lifebook" bring
much more configuration properties to the alsamixer screen compared to
"quanta". "basic" brings "Front Mic" configuration, and "lifebook"
brings "Dock Mick" configuration to the alsamixer screen. Still
scratching. Any ideas?
Regards.
