"FU0F Capture Volume" will still control the volume of rt711 capture. But "FU0F Capture Switch" will be removed. Because DAPM is using this the same node. These is a conflict when we do below: 1. mute "FU0F Capture Switch". And the kcontrol will mute the Corresponding node in codec. 2. use arecord to capture from the rt711-sdca headset 3. DAPM will auto unmute the node which "FU0F Capture Switch" has muted. 4. So we will capture the sound, even "FU0F Capture Switch" shows the state is "muted" (this is wrong) So Shuming decided to remove the "FU0F Capture Switch" kcontrol. > > Anyway, the switch and volume for the given I/O should have identical name > and they should differ only in the suffix describing the stream and > functionality. We won't touch "CaptureSwitch" and "CaptureVolume" for rt711-sdca. The patch will be like what I submitted just now: https://github.com/alsa-project/alsa-ucm-conf/pull/89 Regards, Libin > > Jaroslav > > > > > Regards, > > Libin > > > >> > >> Jaroslav > >> > >>> > >>> Regards, > >>> Libin > >>> > >>>> > >>>> > >>>>> > >>>>> Signed-off-by: Shuming Fan <shumingf@xxxxxxxxxxx> > >>>>> --- > >>>>> sound/soc/codecs/rt711-sdca.c | 8 -------- > >>>>> 1 file changed, 8 deletions(-) > >>>>> > >>>>> diff --git a/sound/soc/codecs/rt711-sdca.c > >>>>> b/sound/soc/codecs/rt711- > >>>> sdca.c > >>>>> index bfb7f1c8ec8f..2a09c305f4e4 100644 > >>>>> --- a/sound/soc/codecs/rt711-sdca.c > >>>>> +++ b/sound/soc/codecs/rt711-sdca.c > >>>>> @@ -652,14 +652,6 @@ static const struct snd_kcontrol_new > >>>> rt711_sdca_snd_controls[] = { > >>>>> SDW_SDCA_CTL(FUNC_NUM_JACK_CODEC, > >>>> RT711_SDCA_ENT_USER_FU05, RT711_SDCA_CTL_FU_VOLUME, CH_R), > >>>>> 0x57, 0x57, 0, > >>>>> rt711_sdca_set_gain_get, rt711_sdca_set_gain_put, > >>>> out_vol_tlv), > >>>>> - SOC_DOUBLE_R("FU1E Capture Switch", > >>>>> - SDW_SDCA_CTL(FUNC_NUM_MIC_ARRAY, > >>>> RT711_SDCA_ENT_USER_FU1E, RT711_SDCA_CTL_FU_MUTE, CH_L), > >>>>> - SDW_SDCA_CTL(FUNC_NUM_MIC_ARRAY, > >>>> RT711_SDCA_ENT_USER_FU1E, RT711_SDCA_CTL_FU_MUTE, CH_R), > >>>>> - 0, 1, 1), > >>>>> - SOC_DOUBLE_R("FU0F Capture Switch", > >>>>> - SDW_SDCA_CTL(FUNC_NUM_JACK_CODEC, > >>>> RT711_SDCA_ENT_USER_FU0F, RT711_SDCA_CTL_FU_MUTE, CH_L), > >>>>> - SDW_SDCA_CTL(FUNC_NUM_JACK_CODEC, > >>>> RT711_SDCA_ENT_USER_FU0F, RT711_SDCA_CTL_FU_MUTE, CH_R), > >>>>> - 0, 1, 1), > >>>>> SOC_DOUBLE_R_EXT_TLV("FU1E Capture Volume", > >>>>> SDW_SDCA_CTL(FUNC_NUM_MIC_ARRAY, > >>>> RT711_SDCA_ENT_USER_FU1E, RT711_SDCA_CTL_FU_VOLUME, CH_L), > >>>>> SDW_SDCA_CTL(FUNC_NUM_MIC_ARRAY, > >>>> RT711_SDCA_ENT_USER_FU1E, RT711_SDCA_CTL_FU_VOLUME, CH_R), > >>>>> > >> > >> > >> -- > >> Jaroslav Kysela <perex@xxxxxxxx> > >> Linux Sound Maintainer; ALSA Project; Red Hat, Inc. > > > -- > Jaroslav Kysela <perex@xxxxxxxx> > Linux Sound Maintainer; ALSA Project; Red Hat, Inc.
