Re: sound configuration on etch??? (usb)

Hi all!

I have some trouble making my usb sound card work as I would like. My
laptop also has a built-in sound card that works ok, but has _very_
_limited_ input sound quality.

What is the proper way to set up and configure sound/alsa on debian etch?

According to the fine manual [1] there's a script to configure sound:
sndconfig - configure sound system

This seems to be gone in etch.

There's also alsaconf, but that doesn't recognize my usb sound card (it
just finds the built-in one of my laptop).

The sound card basically works ok, ie. I can record and play via
'arecord' and 'aplay'. (The best strategy is to have the card plugged in
at boot, to kill artsd once kde is up and then to reload alsa as root.)

However I cannot make audacity work with the sound card. AFAIK, audacity
would use /dev/dsp but though

johannes2:~# cat /proc/asound/cards
0 [USB1648 ]: USB-Audio - PHASE 26 USB(16/48)

1 [Modem ]: ICH-MODEM - Intel 82801DB-ICH4 Modem
Intel 82801DB-ICH4 Modem at 0x2400, irq 11

the usb is 0, audacity only works when the usb sound card is not present
and when the built-in card is 0. Well, the whole idea about the usb-card
was to get better sound quality for audacity et al.

Thanks for any help and/or links to get this work!

It might be worth asking on the alsa-user list. A while back with someone
having problems with a sound card problem on a laptop, I suggested a USB one,
but the reply was that USB ones need a bit of extra work to get them going.
Either look on the archives or post to the list. I think the reply to get
them working was something to do with dmix.

and to post to the list, but you have to register
alsa-user@xxxxxxxxxxxxxxxxxxxxx

Hope you get it fixed.

Nigel.
