Re: [alsa-devel] No sound after suspend-to-ram

26 Oct 2015


      Thanks Kailang, I applied the patch and it works.
I attached again the diffs, before and after PM (with `echo 1 >
/sys/modules/snd_hda_codec/parameters/dump_coef`) so you can see the
coefs have the same values.

Attach is the patch.
Looks good to me.
I'm going to queue it once when George confirms that it works indeed.
thanks,
Takashi

Hi Takashi,
    [ALC275_FIXUP_DELL_XPS] = {
            .type = HDA_FIXUP_VERBS,
            .v.verbs = (const struct hda_verb[]) {
                    /* Enables internal speaker */
                    {0x20, AC_VERB_SET_COEF_INDEX, 0x1f},
                    {0x20, AC_VERB_SET_PROC_COEF, 0x00c0},
                    {0x20, AC_VERB_SET_COEF_INDEX, 0x30},
                    {0x20, AC_VERB_SET_PROC_COEF, 0x00b1},
                    {}
            }
    },


Could I put code as upper? Was it enter to initial state?
I think it should be execute atfter resume back. Right?
Yes, these are performed at resume.  But the COEF stuff needs
a bit care since it's written in multiple places.  If you can
cook up the patch, I can check it hda-emu, too.
thanks,
Takashi
