I don't see that. Some people might want to be able to use multichannel on RPi, but that's something very different than adding code that just lies about driver capabilites.I am going to invite you over for dinner to eat steamed vegetables :) If I make the steamed vegetables in the microwave and they taste like steamed vegetables, are they steamed vegetables ?If you connect an amplifier with a volume control to your soundcard does that mean that your soundcard now has a volume control? No, your amp has.quoted
I have a bcm2835 (Pi 2 and 3) SoC here. It is producing multichannel (8 out, 6 in) audio. In ALSA we call that DSP mode - right ?!No. DSP modes are protocol/timing specifications as I2S, PDP, S/PDIF, ... You can look these up in datasheets and if a chip implements such a protocol you can be sure that it adheres to that standard - i.e. it will sync the frames to the pulses on LRclk.
I agree with the thoughts in this thread really if the AP doesn't actually support DSP A mode we shouldn't add DSP A mode. Thanks, Charles
