asoundrc problem

[Oliver Schrempf]

Since my last mail where I sent my current settings I still have the
problem, that I recieve the following error message

arecord: main:462: audio open error: No such file or directory

when trying
arecord -Dplug:multi -c 16 -t wav test.wav

what shows if you run "aplay -L" and "aplay -l" ?
does pcm.multi appear there?

OK, the modules where not loaded :-(

hmm..  does it work when you specify the format and rate?

	% arecord -Dplug:multi -c16 -fS16_LE -r48000 foo.wav

(or -fS32_LE as a native format, then you don't need plug layer)

also, try whether areocord (with -c 8) works on each card (hw:0 and
hw:1).

None of that works, always the same error as above

It works with -Ddefault
 or with -Dice_a and the following pcm
pcm.ice_a {
        type plug
        ttable.0.0 1
        ttable.1.1 1
        ttable.2.2 1
        ttable.3.3 1
        ttable.4.4 1
        ttable.5.5 1
        ttable.6.6 1
        ttable.7.7 1
        slave.pcm {
                type hw
                card 0
                device 0
        }
}

-Dhw:0,0 gives
arecord -Dhw:0,0 -c8 -fS16_LE -r44100 foo.wav
Recording WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Channels 8

it's the expected behavior, because the hardware doesn't support this
format.  it suppors only S32_LE.

but it seems that this is an alsa-lib bug although i can play
4-channel wav file using two consumer cards...

OK, I understand this, but when I use
% arecord -Dhw:0,0 -fS32_LE -r48000 foo.wav
I get
arecord: set_params:792: Channels count non available

Is this expected, too?

Hmm? Can I help here? I'm no expert in alsa-lib, but I can test on my
hardware. Let me know if you need something.

yes.  the number of channels must be 10 for your card.

well, this might be because you specfied 8 channels instead of 10.
the hardware supports only 10 channels natively.

could you check whether 20 (10+10) channels work?

One interesting thing is, that it works with -Ddefault
There I can specify as many channels(1-10) as I want and it works.
With -Dhw:0,0 -c10 again there comes
set_params:792: Channels count non available

Can I find out what the alias default stands for?

I also tried to extend the multi slave to 2x10 Channels, but that doesn't
work either.

Sorry, but I can't find any documentation on "plug:multi"?

aplay -Dplug:multi

It's device description/name for alsa-lib.

Thanks for that one, but

arecord -Dplug:multi -c16 multitest.wav
gives me

hmm, there is still a bug in the alsa-lib configuration parser..?


anyway, add the following and try -Dmplug instead as a workaround.


pcm.mplug {
	type plug
	slave.pcm "multi"
}

Umpf, sorry. I just realized, that I had a mistake in asoundrc from
playing around with plug:multi.

The error I get now from
arecord -Dmplug -c16 test.wav
as well as from
arecord -Dplug:multi -c16 test.wav

is

arecord: main:462: audio open error: No such file or directory

did you still have your original definition of pcm.multi ?
the setting above is additional one.
