USB Audio Sound Adapter Not Working

Rog3236 · 05-10-2009, 11:51 AM

I am a Newbie running Ubuntu 9.04. I have no problems with the sound card, however, when I connect a PD552 USB sound adapter into a 4 port hub in order to use headphones it simply doesn't work. I posted the problem on the Ubuntu site and received a suggestion to run lsusb from a terminal. I did this but never received any other replies addressing the issue.

This is what I receive from the command. It shows up as device 7 but I have no idea of what my next steps are to insure it will work.

~$ lsusb
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 007: ID 1130:f211 Tenx Technology, Inc. USB audio headset
Bus 001 Device 003: ID 0930:653e Toshiba Corp. USB Flash Memory
Bus 001 Device 002: ID 050d:0234 Belkin Components F5U234 USB 2.0 4-Port Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Any help would be appreciated.

Try plugging it in directly (not into the hub)
Try plugging it into a powered hub.
Take a look at the output of lsusb -v (Please don't post it all here). How much current does your audio headset want to take?

Connecting it directly to a computer USB port made no difference. Running the suggested lsusb -v command showed a max power of 500ma.

When plugged into a powered 4 port Belkin USB Hub max power shown is 2ma.

I am out of ideas, and do not have the hardware that is causing you problems, so it is difficult for me to help you.

This link may help: http://www.linuxquestions.org/questi...41#post3186541

When you read that thread, please substitute "USB Speakers" for "USB Headphones". You may have to experiment a bit.

Good luck.

Which version of alsa are you running?
cat /proc/asound/version

Should give the version.

Command cat /proc/asound/version came back with:
Version 1.0.18rc3

I had to upgrade to 1.0.20 to get my USB sound card to work, currently using 1.0.20-git20090509. I'm not exactly sure how best to do this in Ubuntu I suggest you try google, it might be as simple as adding a new source to apt or something. Otherwise it can be done from source.
