Volume quiet on LyraT 4.3

[jonzobot]

Hi Carlos,

As requested under issue #68, that commit appears to have created a small problem relating to volume on LyraT 4.3. Specifically the volume levels have been reduced substantially. It may be that the fix and config changes for that issue may need to be limited to the board in question, i.e. AI Thinker. It is probably not an issue if one is using an external amplifier, but I am using the on-board amp.

I had to uncomment https://github.com/CarlosDerSeher/snapclient/blob/master/components/audio_hal/driver/es8388/es8388.c#L462-L468 this section to restore audio volume on my Muse Luxe

Disregard that, i gaslit myself again

More real fix is to add reg -= 0x0c after https://github.com/CarlosDerSeher/snapclient/blob/master/components/audio_hal/driver/es8388/es8388.c#L442

and change 0x1E to 0x21 here:

@hjri what do you think about just reverting back to the original ADF driver and modify it only for AI thinker board? And what does this reg -= 0x0c do?

[hjri]

It's been a long time, i don't remember exactly, according to documentation it should set amplifier gain to 0db instead of -3db or something, and it's still quiet

haven't experimented since, especially since snapclient just sorta dies after a while

[CarlosDerSeher]

Ok then I'll just revert to the original driver and add the diff to the current one only for AI thinker.

And what do you mean by it dies? Did you try current master? Or you could try fix_20ms branch which is the newest implementation with some bug fixes.

[CarlosDerSeher]

@hjri if you find time you you could try this and see if it makes things better for you

[hjri]

i'll give it a try and also compared to one of the "stock" firmwares as well just to confirm i'm not gaslighting myself
