After the mentioned Kernel upgrade quite a view things went wrong on my hardware ( http://www.asrock.com/mb/overview.asp?Model=890GM%20Pro3 ):

• Microphone doesn't work anymore. neither the front mic nor the rear

one. Tried all thinkable settings.

• Increasing Microphone levels leads to some strange internal feedback.

That means, at some point when the feedback starts, it just starts, but i

have

...

...

no clue what audio source did actually trigger it.

• Touching the mixer channel "Smart 5.1" in alsamixer makes alsamicer

crash.

Refer to the user manual , the motherboard has 5 audio jacks in rear

panel,

...

7.1 need retasking of Line in (blue jacks) as side

Audio Output Channels Front Speaker Rear Speaker Central / Bass Line In (No. 9) (No. 6) (No. 5) (No. 8) 2 V -- -- -- 4 V V -- -- 6 V V V -- 8 V V V V

Forgive me, but i don't understand. I hope this doesn't mean i have to solder on my Mainboard if i intend to use a newer kernel.

If there is something i can do, please explain in more detail.

Smart 5.1 is for 3-jacks model, to reuse input pins as outputs. While off, they act as "line out" / "line in" / "mic in". While on, they acts as "line out" / "back left/right" / "center/lfe".

If the driver use "Smart5.1 switch" for those 5-jacks model, you will need to modify the function is_smart51_pins()

static int is_smart51_pins(struct via_spec *spec, hda_nid_t pin) { const struct auto_pin_cfg *cfg = &spec->autocfg; int i; if (cfg->line_outs == 4) return 0; for (i = 0; i < cfg->num_inputs; i++) { if (pin == cfg->inputs[i].pin) { switch(cfg->inputs[i].type){ case AUTO_PIN_LINE_IN: return (cfg->line_outs == 3 || cfg->line_outs == 1); case AUTO_PIN_MIC: if ( strncmp(hda_get_autocfg_input_label(spec->codec,cfg,i),"Rear Mic",8) == 0 ) return (cfg->line_outs == 1); } } } return 0; }
