Hacking Audio on N Switch and available services

[Alklas]

Hello,

i've been digging in the audio capacity of the switch, i read the Tegra TX1 official documentation, which is really low-level, and the TX1 has a lot of possibilities in its sound "chipset"
but in the sub-services available in the Switch OS, under the audio service, are really limited, and i'd like to know if i understand well : as the service only allow to play a sample, does it mean that programmers have to make their own mixer, and so their own library to handle music channels + sounds in games ?

You should read the sdk docs instead of the TX1 docs.

are you talking about the Nintendo Switch official sdk ?
i checked the test example for audio available in libtransistor, and it only shows the few audio services listed also on switchbrew.

Official yes.

hello again

seems i am not able to find the official SDK
anyway, i have another question : services for audio module only lists a few services, am i right when i think that if i want to go deeper in the switch, for example using directly the audio 'chipset', that won't be possible because pegaswitch only allows userland programs ?
accessing the audio registers must be kernel level ?

Would compressed audio output have a big effect on the CPU if Nintendo wanted to offer the chance for a user to buy a Dolby Digital license to enable 5.1 audio .

It’s a stupid question I know.
