Hi Takashi,
While working with fixing the stuff that my automated test tool has discovered, here's one I'm not sure what to do with.
If you run hda-emu on any of these three:
codecs/canonical/stac9200-dell-inspiron-6400-ccert-200705-83 codecs/canonical/stac9200-dell-inspiron-6400-ccert-200712-207 codecs/canonical/stac9228-dell-inspiron-1420-ccert-200708-95
Hda-emu prints out: invalid command: NID=0x1, verb=0x7e7, parm=0x0
In this case, I'm not sure if the command is invalid (and thus should be removed), or if it's a secret IDT verb that we need to set.
From patch_sigmatel.c:
/* Configure GPIOx as CMOS */ snd_hda_codec_write(codec, codec->afg, 0, 0x7e7, 0);
But in hda-spec.c this verb is only in the verb table of IDT codecs, not STAC codecs.
Can you offer some enlightement?
