What I mean is a software / hardware solution. I've been doing a bit of reading about what the Windows monkeys are doing and it seems to typically involve at least two of these three adjectives: complicated, expensive, unstable, technically inadequate (e.g. using multiple DACs with no regard to clock syncronization).

ok, free in linux

if you script your well-tested equalising chain to start reliably, than I would say stable

That is a hardware issue, common to all OSes. In linux it is easier to merge soundcards though.

Woldn't it be possible to use one of the mulichannel dac projects here on diyaudio for this purpose?

IMO multichannel output is no major problem in linux, there are numerous multichannel soundcards, USB adaptive DACs can be safely merged using the multi alsa plugin (the major linux advantage), etc.

Hi folks.

I'm playing around with a tiny Android 4.1.1 device.

I just hooked up my good old EMU 0404 USB to it.

It was immediately recognized.

The problem is now that I'd need amixer (alsa-utils) to set the samplerate.

It seems that nobody is considering alsa-utils a useful package for Android.

Question: Is it possible to set the driver parameters that are usually set via amixer also diretcly via /proc/asound ??



Thx

Cheers

using multiple devices as a composite audio device (called aggregate audio device) has been possible in mac OS for many years, or you speak of an advantage vs windows?

Yes, I see windows users fighting such setup all the time.

This thread: [android-porting] ALSA on x86 - No sound may hold some clues for you. They mention alsa_mixer and saving the settings in /system/etc/alsa_config.

Well, after a bit more poking around I'm tempted to just get a Delta 1010 and have a go at it. I'm also thinking that something like the nanoDigi into a Buffalo-III would suit.
