Hello there,

just upgraded to kubuntu 9.04 with KDE 4.22 ... and now I am facing
a problem a saw with 8.10, too ... but I forgot how to resolve it.
And maybe there is a good explanation around for this; and by talking
about it I will remember for the future.

I got a usb headset plugged into my docking station; and it is working fine for me.

I can see it in the "system settings"->"multimedia" panel ...
and I configured ALL Audio Output/Capture device prefences to "prefer"
my headset.
(and with kmixer, I enabled the "auto gain control" for the headset)

So, when I start amorak to listen to MP3s ... sound from the headset. Fine.

But for any video inside a browser (opera/firefox/konquerer) ... sound
keeps coming from my laptop speakers. Same for notification sounds
from applications like Lotus Notes (not that I care about that; but
the video sound is annoying).

So, what is missing?

Have a look at This page.

At the bottom there's some info on setting the default sound device that may help. :shade:

It says there:

External soundcards If you have an external soundcard (e.g. a USB sound device) you will have to explicitly select it as default.
(asoundconf set-default-card "name of soundcard")
where your "name of soundcard" is seen in square braces in the output of:
(cat /proc/asound/cards)

The later one says:
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xfe220000 irq 17
1 [default ]: USB-Audio - C-Media USB Headphone Set
C-Media USB Headphone Set at usb-0000:00:1a.7-4.1, full speed

So, the headset is already the default.

Try

Code: Select all

sudo asoundconf set-default-card default

and reboot.

If that doesn't help look here for another way to try.

Surprise; it did help.

Now I am wondering what will happen tomorrow when I will be
using my machine from home ... with a different type of headset

Thank you very much!
