Kindly add device ID 0x1025 0x0146 to the quirks list in patch_realtek.c . Jack detetction and playback is working without any hda-verbing. Just the internal mic seems to be a problem. Can't hear my voice, can just hear static when I playback a recording. Anyways big thanks to Hector and Takashi for getting it all to work.

If yes, there should be a slight difference between 6935G and 8930G... thanks, Takashi ^ permalink raw reply [flat|nested] 4+ messages in thread

Karthik: please look in sound/pci/hda/patch_realtek.c and locate the alc889_acer_aspire_8930g_verbs array. At the end, where it talks about the "DMIC fix", find the last verb: {0x20, AC_VERB_SET_PROC_COEF, 0x0003}, And change the value from 0x0003 to 0x0001 and see what that does. If this works and you get some audio, make a stereo recording. You want both channels to be of equal volume. I suspect you have a mono mic on the left channel. I have a stereo sum/difference mic (WTF) with sum on the right channel, so I tweaked the setting to replicate the right channel to both. This would kill your audio if your microphone is just a mono one on the left channel. Setting 0x0001 should get you standard stereo audio as it comes from the mic(s). I think setting 0x0002 should get you what you want (left channel replicated to both channels). If not, try setting 0x0000. Takashi: if I'm right, we'll need two model entries instead of one and we should probably split off the verb array into three (base, stereo sum/dif mic fix, mono mic fix). -- Hector Martin (hector@marcansoft.com) Public Key: http://www.marcansoft.com/marcan.asc ^ permalink raw reply [flat|nested] 4+ messages in thread

Right. And, IIRC, some other Aspire laptops such as Aspire One have a similar problem (the stereo differential from a PDM mic module), it'd be a good workaround, too. We need to check that, too...
