Hello all,
A long ago, I said on this list (I think), I had the intention to write
a graphical mixer/router for the EMU 10k cards (EMU 1212m & EMU 1616m).
I wanted to make a nice, well-written, full-featured app with routing
levels and eventually effects and all, but couldn't figure out all the
intricacies of the card's driver.
So, over the last two nights I hacked together a simple "Matrix"-style
app, very ugly in code, but functional, for me, at least.
I won't have time to maintain it, but if you want to try it out, at the
end of this message you'll find links to a screenshot, the source
package and an x86_64 build. You'll need Qt & ALSA libraries, of course.
Be aware that many features are missing, but basic routing works. I'll
put up a version control repo when I have time.
Any comments welcome.
Greetings,
Camilo

And maybe, EMU 1810.
Hi hermann,
Thanks for the feedback. I made a lot of assumptions from my own card
and installed driver & not a lot of sanity checks. Is your card EMU 1010
based?
What's the output of the "amixer info" command?
My own is a EMU 1212m (old PCI version), amixer info:
Card default 'EMU1010'/'E-mu 1010 [MAEM8810] (rev.3, serial:0x40011102)
at 0xc000, irq 16'
Mixer name : 'SB Audigy'
Components : ''
Controls : 239
Simple ctrls : 80
I am no expert on ALSA or EMU soundcards, so I don't know the
differences among cards and drivers, but will code some checks now, to
make sure it doesn't crash that easy.

Camilo

Also added a few tests and some "sane" defaults.
Warning: if you run it, it will turn a lot of your levels down, and some
up. Should be easy to correct afterwards with alsamixer, but to be on
the safe side, store your driver configuration with
alsactl -f mixer.bak store
before testing.
It is also worth mentioning that the program ignores all those pesky
"PCM Multichannel Routing/Volume" and similar mixer elements. If they
are not set as per driver default, it may not work. If someone has any
idea how those work, please explain.
