no sound in Firefox/flash and Pidgin

[pansz]

Kubuntu 10.04 32bit.

I've got an external sound card and had disabled the internal sound card in BIOS.

In Kubuntu everything works, Skype has sound input/output and amarok works.

But my gtk applications such as firefox (and the flash in Firefox) and pidgin has no sound.

Any hint? Thanks.

Re: no sound in Firefox/flash and Pidgin

Firefox and sound, including flash vids, work fine on my 10.04 32-bit install. What sound card/device do you have in your rig? What Backend (System Settings > Multimedia > Backend) are you using?

Re: no sound in Firefox/flash and Pidgin


I'm using the default backend: Xine

The sound card is a USB one: C-Media USB Headphone Set

This works for KDE and Qt applications, but does not work for gtk+ applications and SDL games.

Try and go to your mixer settings and see if the "PCM" volume is muted. For some reason my firefox does this every time I have a fresh install of Kubuntu.

I'm using a USB sound card and there are no PCM channel at all.

In kmix there're only three channels:

Mic, Speaker, Auto Gain Control.

With the onboard sound card there is a PCM channel, but my onboard card has no sound for 3 years (That's the reason I buy a usb sound card)

I also noticed that alsamixer cannot found the mixer at all:

$ alsamixer 
cannot open mixer: No such file or directory
