Please help

The problem I'm having is. I Get no sound when playing music in vlc or any other player like Mplayer in Ubuntu.

the motherboard is a jetway j7f4 board.

The OS is Ubuntu Linux mythbuntu 8.10 debian version - lenny/sid.

I tested the machine on a live puppy linux cd it all works fine.

So It's definetly a problem in ubuntu.

this is what I have done so far.

I had a look at this web site.
http://www.seopher.com/articles/how_...op_or_notebook

And they said to disable the external amplifier tick box, and it should solve the problem.
But it didn't.

So then I had a look at this web site.

And I was able to get these details on my sound card.

# aplay -l

Code:

**** List of PLAYBACK Hardware Devices ****

Lspci -v

Is alsa working correctly?? Try running alsaconf from command line. It would also help if you posted the type of computer you are having the issue with.

if it's a desktop the answer could be as simple as disabling your onboard sound in the bios

I managed to fix the original problem with the internal soundcard.

I install a new mixer gui and now the internal sound card is working.

however the sound quality is really poor.

So I have disabled the internal soundcard and connected a Egosys U2A USB soundcard to the PC.

This soundcard is supposed to be linux compatable. but I am unable to get it to work.
The sound card has power but there is no sound.

I have tried the aplay -l and no device is listed.

I have also tried the Lspci -v command but I am unable to see the soundcard listed.
if i run lsusb I get this

# lsusb

Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Is there anything I can do to improve the sound quality with the internal soundcard.

Or how do I get the USB sound card to install properly.

Has anyone any idea's I can try.

Don't know if you've tried visiting the mfg's site for the linux driver. If the card is supposed to be linux compatible they should have a driver for it or, if you received a driver disk with the soundcard have a browse through it and see if there is a linux folder.
