Hi Takashi,
This patch also changed model name as 'alc-chrome-book'. It also tested by Intel Chrome audio team.
BR, Kailang

Hi Takashi,
You applied below patch. https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit /?h=for-next&id=c8a9afa632f0fd45731d3353525faf1fdb362c89
But I think ALC225_FIXUP_HEADSET_JACK will applicate for enable for headset button. It was not only use for Chrome OS. So, ALC225_FIXUP_HEADSET_JACK and alc295_fixup_chromebook separation were be better.
Intel test https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?h=fo... this patch. Mic JD was also not stable. (I don't know why. It passed with Ubuntu OS.) It need to change to initial state would be better. (original was HDA_FIXUP_ACT_PRE_PROBE)
+static void alc295_fixup_chromebook(struct hda_codec *codec,
const struct hda_fixup *fix, int action) {- switch (action) {
- case HDA_FIXUP_ACT_INIT:
switch (codec->core.vendor_id) {case 0x10ec0295:alc_update_coef_idx(codec, 0x4a, 0x8000, 1 << 15); /* Reset HP JD */alc_update_coef_idx(codec, 0x4a, 0x8000, 0 << 15);break;case 0x10ec0236:alc_update_coef_idx(codec, 0x1b, 0x8000, 1 << 15); /* Reset HP JD */alc_update_coef_idx(codec, 0x1b, 0x8000, 0 << 15);break;}break;- }
+}
How could I create a fix patch for this?
The Chromebook quirk name was chosen so that the quirk implementation won't be used by any random user as a generic solution. If it can be used for real solutions, feel free to rename / split the quirk for easy adaption. I have no big preference, but would like to judge from the actual patches.
thanks,
Takashi
