Hello, for those of you not subscribed to LAD, I finally got to write a mixer application for the EMU 1010 based cards. I tossed out the original ideas of a full-featured app and went the simple way, just basic point-to-point routing, no fancy "Multichannel" features.
It's available here: http://code.google.com/p/emutrix/ Screenshot: http://www2.udec.cl/~cpolymeris/emutrix/Screenshot-EMutrix-1.png
Be aware that the code is awful, just fast prototyping, but functional. It may also mess with your mixer levels, if you want to try it. please make a backup with 'alsactl store'.
Feedback welcome, Camilo

Hello.
On my card, playback channels 1 & 2 (hw:0,3) appear on all DSP busses associated with surround. Say you turn up the "Side" fader in alsamixer, channels 1 & 2 will appear at the relevant DSPs (6-7, I think) Whatever, for now I am just keeping all surround controls down (that is, Front, Surround, Center, Side & LFE).
I see, you talking hw:0,3. Perhaps this will help: http://www.mjmwired.net/kernel/Documentation/sound/alsa/Audigy-mixer.txt http://www.mjmwired.net/kernel/Documentation/sound/alsa/emu10k1-jack.txt
I think the switches and enums for the card models are rather trivial, one can handle it with a customized version of qamix (done with a simple XML file), for example. A separate application would not be necessary for only that.
I disagree. With all the switches, routing, sample rates and several models, the EMU is one of the most complex cards. Definitely more complex than Envy24, Echo or perhaps even RME/HDSP. All these cards have their appliactions in alsa tools.
By the way, only DSP0-7 work in this way. I have no idea how to make DSP8-31 work.
You cannot do that without a driver modification. There is no any EMU specific code for hw:0,3. It somewhat works thanks to DSP code in hw:0,0, which copies data from emu10k registers to DSP0 to DSP7 ports.
Personally, I'd like to have an 8 channel 24bit playback on hw:0,0 with all the fader stuff for consumer playback and then another device (modified hw:0,3 or even a new one) for (at least) 16 channel 24bit playback directly passed onto DSP buses.
