usb soundcard no audio mixer crash

simon72post · 03-07-2009, 06:22 AM

Hi
I have been trying to get my USB soundcard working on my Mythbuntu 8.10 computer.
The soundcard is a ego-sys U2A soundcard and is detected, but I dont have many controls in the default mix I only have mic input. and the soundcard dosn't even have a mic input.
I have tried various other mixers but they crash when I try to use them. so I'm unable to get any sound out.
I have read that there is no volume control with this card which isn't a problem so long as I can set the volume high and get some sound out of it.

dos anyone have any idea what I can do to fix the problem.

thanks Simon

hi

I do not have your hw so forgive me for replying after only 18 hours or so.

I think the issue is your capture device may be hogging the sound server.

the answer may be to configure a different sound server such as pulse or
http://jackaudio.org/ http://www.64studio.com/

you may want to run alsa-info.sh and look at www.alsa-project.org for a .asoundrc file or send a mail to the user mailing list?

Hi

Thanks for the response.

The other Device Bt878 Audio Capture is a DVB TV card.
I removed this card and rebooted the machine but was still unable to get and audio out.
All I get are a few clicks while booting.

From what I have read the volume is not adjustable on this sound card. So I'm thinking if the system has set the volume half way it's causing the problem.

Is there a configuration file somewhere where. where I can adjust the volume to maximum and that might solve the problem.

As all the mixers I have tried crash.

Thanks

Simon

try alsamixer as root and then as a user
maybe its a permissions thing with your distro?

Hello Again

I have been having more of a look and have still not been able to get any audio out.
I have checked the permissions and my user is in the list.

I found this infomation about this soundcard
http://www.qbik.ch/usb/devices/showdev.php?id=969

And it said as the volume has no control in linux. and to adjust the volume in windows then plug the soundcard in to linux.

I tried this but still no luck (worked fine in windows though)

here is a bit more infomation.

hmmm google is not friendly with this usb device.

I am struggling...maybe download the ms driver and run it with wine, using an xp driver?
