AIDL devices and some questions

[AlexSagit]

Hello, dear Zyhk! Your module is wonderful, it really boosted audio-quality of my device. But I mean the scripts in /extras folder. And is there any news about adding support of the main script for AIDL-only devices, which my is? Can't wait for it :)

Also, maybe you could add some tweaks of A-Box(or Alsa, Aaudio, Asound) in this scripts-combo, or in another one. It can also significantly improve sound quality. Now, i tweak Alsa(and more) with many parameters in Tinymix Manager, but the settings are reverting on each reboot or device connection. Maybe, i could make my own script in that case, but you could give to people your mix of best proven settings(applying on boot or device connection), cause there are many of all them.
Also, i could recommendate you some of the settings, if you need this :)

Best regards, your Alex

I don't have any AIDL only device now, and the support hasn't progressed.

Can you explain more about your settings for ALSA and Tinymix manager?

Oh, very cool that i could help you with my settings!

The most effort in sound quality are giving parameters "PREGAIN", "POSTGAIN" and "AMP"(all of them are disabled by default), also "Channel"(i think, that means cores of CPU, through which the sound goes. Default is 2 and I enabled 7 of 8, but with every connection of my usb-dongle or bluetooth some of them are resetting) and "Soft Ramp"(Default is 0.5ms. According to my hearing, that is a sort of smoothing of the sound).
The "PREGAIN" alone gives much more sound transparency, but the elaboration and clarity of discrete images are becoming worse. The "POSTGAIN" and "AMP" are preserving transparency of "PREAMP", but highly improving elaboration and clarity, so that you can "touch" the instruments and effects. With "Soft Ramp" tweaked to "disabled" you can distingiush all the music immediately as it goes, instead of after a slight delay. Some of the "Channel" settings are improving general elaboration.
UPD: "Channel" settings are dangerous, many of them can break the sound

Additionally, i disabled "Dummy Start", "VPBR"(this is sound limiter), "DSIF PLA DSIF", "TONEGEN_1KHZ"(some strange thing), "HPF", enabled "Boost" on both stereo outputs and set "HPF SEL" to 40Hz instead of 120 as in stock(i just like this number more😁). That are params, which don't have an obvious effect on the sound, but i just wanted to disable unnecessary sound processing, tweak more and look where it will go :)

Also, of course, I could help you with AIDL-only support by means of my device!

Please give me some time, and I will consider what I can do and cannot.

[AlexSagit]

Sure! But i can update my advices, based on my new observations. The "channel" settings are dangerous. Also, they don't affect sound in a good way, as well as disabling "VPBR" and enabling "Boost". The rest makes sense, especially "Pregain", "Postgain", "Soft Ramp" and "Amp", but the last one of them resets on each device connection, and "Pregain" sometimes too(i don't know, what does it depend on). I hope, that i'm not annoying you too much🥺 Best regards :)
