[PATCH] ASoC: sgtl5000: Revert "ASoC: sgtl5000: Fix of unmute outputs on probe"

[PATCH] ASoC: sgtl5000: Revert "ASoC: sgtl5000: Fix of unmute outputs on probe"

[Alison Wang]

This reverts commit 631bc8f0134ae9620d86a96b8c5f9445d91a2dca.

In commit 631bc8f0134a, snd_soc_component_update_bits is used instead of
snd_soc_component_write. Although EN_HP_ZCD and EN_ADC_ZCD are enabled
in ANA_CTRL register, MUTE_LO, MUTE_HP and MUTE_ADC bits are remained as
the default value. It causes LO, HP and ADC are all muted after driver
probe.

The patch is to revert this commit, snd_soc_component_write is still
used and MUTE_LO, MUTE_HP and MUTE_ADC are set as zero (unmuted).

[Oleksandr Suvorov]

Alison, could you please explain, what reason to revert this fix? All
these blocks have their own control and unmute on demand.
Why do you stand on unconditional unmuting of outputs and ADC on driver probing?

Hi, Oleksandr,

I think I have explained the reason in my email which sent to you yesterday. I attached it too.
According to my test on the boards, MUTE_LO, MUTE_HP and MUTE_ADC are all muted when
playing the sound.

Could you give me some ideas about this issue?

Hi, Oleksandr,

I have a question about this patch. Could you give me some ideas? Thanks.

In this patch, snd_soc_component_update_bits is used instead of snd_soc_component_write. Although EN_HP_ZCD and EN_ADC_ZCD are enabled in ANA_CTRL register, MUTE_LO, MUTE_HP and MUTE_ADC bits are remained as the default value. It causes LO, HP and ADC are all muted after driver probe. BTW, in the original code, snd_soc_component_write is used and MUTE_LO, MUTE_HP and MUTE_ADC are all set as zero (unmute).

I saw the above phenomenon on the latest linux-next. For LO and HP are muted, no sound can be heard.

Alison Wang

[Alison Wang]

Hi, Oleksandr,

In your patch, outputs and ADC are muted on driver probing. I don't know when and
where they can be unmuted in the kernel before playing in the application.

Could you please give me some ideas?

Re: [EXT] Re: [PATCH] ASoC: sgtl5000: Revert "ASoC: sgtl5000: Fix of unmute outputs on probe"

[Oleksandr Suvorov]

They unmute with standard sound controls:
static const struct snd_kcontrol_new sgtl5000_snd_controls[] = {
...
SOC_SINGLE("Capture Switch", SGTL5000_CHIP_ANA_CTRL, 0, 1, 1),
...
SOC_SINGLE("Headphone Playback Switch", SGTL5000_CHIP_ANA_CTRL, 4, 1, 1),
...
SOC_SINGLE("Lineout Playback Switch", SGTL5000_CHIP_ANA_CTRL, 8, 1, 1),
...

We tested this standard solution using gstreamer and standard ALSA
tools like aplay, arecord and all these tools unmute needed blocks
successfully.

Marc / Oleksandr,

I can't seem to find the original patch in my mailbox for 631bc8f:
('ASoC: sgtl5000: Fix of unmute outputs on probe') however I find it
breaks sgtl5000 audio output on the Gateworks boards which is still
broken on 5.6-rc6. Was there some follow-up patches that haven't made
it into mainline yet regarding this?

The response above indicates maybe there was an additional ALSA
control perhaps added as a resolution but I don't see any differences
there.

Best Regards,

Tim

I forwarded you that one again. OK?

What exactly do you mean by "breaks"? Isn't it that you just need to
unmute stuff e.g. using amixer or using a proper updated asound.state
file with default states for your controls?

I don't think so. It all works perfectly, not?

Not that I am aware of, no.

The response is talking about existing controls that are already in the
driver.

the audio device is in /proc/asound/cards but when I send audio to it
I 'hear' nothing out the normal line-out output.

The output of 'amixer' shows nothing different than before this patch
where audio out worked (same controls, same settings on them). I'm
testing this with a buildroot rootfs with no asound.conf (or at least
none that I know of... i'm honestly not clear where all they can be).

Tim, did you try to unmute the output with amixer?

Could you provide the output of your amixer with and without this patch?

Before this patch, the driver unmuted HP, LO, and ADC unconditionally
on load (while it just had to set up ZCD bits).
Now HP, LO, ADC remain muted until one unmutes them using standard
ALSA tools/interfaces.
ALSA mute/unmute controls for these outputs have been presenting in
the kernel for a long time. Please, just use them.

Oleksandr,

When I first bisected to this I must have done something wrong as I
thought amixer settings showed the same before and after - I see that
I'm wrong about that. I see the differences now with HP, LO, and ADC
muted by default. I agree using amixer controls is fine.

Sorry for the noise!
