Re: [Alsa-user] Sound Card Configuration

I tried that, that particular suggestion didn't work,
It assumes that you use the default dmix configuration for your
sound card.
but I changed it to
pcm.!default rear:Live and
pcm.!default front:Live
which did work partially. However, it broke sound in firefox. It also
messed up some flash programs.
The front and rear devices do not do sample rate conversion or
software mixing.
Also, I was hoping to get the devices X session dependant. I heard someone
suggest chrooting each X session, copying the dev directory and linking
/dev/dsp to /dev/dsp[x] (whatever number card you want for the given X
session).
That suggestion is for programs using the OSS interface, but your
description above shows that Firefox and Flash use the ALSA interface,
so you should be able to get this to work with ALSA configuration files.
If you set an environment variable ALSA_DEVICE to 0 or 1 for each
session, the following definition in /etc/asound.conf should do what
you want:
pcm.!default {
type plug
slave.pcm {
@func concat
strings [
dmix:CARD=Live,DEV=
{
@func getenv
vars [ ALSA_DEVICE ]
default 0
}
]
}
}

Yes, but only if the hardware supports this. If not, use some program to record and play the same data back.

Re: [Alsa-user] audio loopback in linux
Hi! I'm not sure, if alsa does it, still. But you can do it with jackd (Jack Audio Connection Kit). It's a low latecny audio server and a lot of Linux Audio software support it. You can find packages in your distro. Then you simply do: jack_connect system:capture_1 system:playback_1 jack_connect system:capture_2 system:playback_2 Or install some GUI connection tool, e.g. qjackctl.

[Alsa-user] SuSE issues
I've posted before about this, and got that I was not giving enough information. What was needed, or how to get it, I do not know. This laptop computer runs a 1.83 GHz, 2-channel Intel processor(s) in what was sold as a System 76 Pangolin. Whatever OS I run it is a long guessing game of installing, or removing, the right files to actually get sound from the thing. So far, having switched from Ubuntu to SuSE over keyboard driver issues, I have gotten exactly nowhere. If anybody can offer why this is a problem, what info I need, how to get it, or what to do with it, I would be most grateful.

On that card it shows as H/W H/W 1 H/W 2 H/W 3 and you just change it from PCM Out to HW In 0 or whatever source you want. Bear in mind that if input is a mic and the speaker is loud enough you'll get feedback. And if you're doing it for some sort of TV Capture card that audio has less latency than video, so you'll hear them talk before their lips move (just slightly) which can/will drive you nuts.
