no audio

[WANT2LEARN]

I have no sound when I connect headphones or speakers , I have knoppix 6.3 installed ?

root@Microknoppix:/home/knoppix# cat /proc/asound/cards
0 [V8237 ]: VIA8237 - VIA 8237
VIA 8237 with unknown codec at 0xe000, irq 22

You may be unlucky with your VIA chipset as it has an unkown codec. TRy:
sudo apt-get update
sudo apt-get install win32codecs
