Re: knoppix and audio

[Marcin Lach <marcinlach@gmail.com>]

Hello

Laptops with 2 sound cards usually have one card digital for hdmi and second analog witch is connected to speakers.
I wonder if a startup script could find witch one is analog and then create .asoundrc file in knoppix home directory setting analog as default card

It's difficult. The sequence in which cards are detected is usually
their time of detection and loading of the corresponding sound module.

There is a possibility to configure the numbering of sound slots by alsa
sound module options, but this has to be done manually. I'm looking for
a lightweigth ALSA configuration gui, the ones of gnome and KDE seems to
heavy and need all kinds of additional services started in order to run
properly. :-/
