volume control not working w/ spdif

[illumilore]

I am using optical output and just installed oss4 on ubuntu karmic. I managed to get it working with spdif by using the ossxmix application, but other than the spdif play checkbox, nothing seems to work elsewhere. None of the volume sliders or volume output level indicators work. Is there also a way to get the gnome volume control applet to control oss4?

EDIT: Use this PPA to run GNOME in Ubuntu Karmic w/o PulseAudio: https://launchpad.net/~dtl131/+archive/ppa

On Ubuntu 9.10, I have not yet figured out how to get the GNOME volume control working w/o Pulseaudio. You can always use scripts and key bindings though: http://www.opensound.com/wiki/index.php ... rol_volume

I'll be looking into this issue more extensively soon.

Hi Temüjin!

Have you tried "xfce4-mixer"?

sudo apt-get install xfce4-mixer

It works without PulseAudio on Ubuntu 9.10, and it has "spdif" controls.
I just tested it on my old box.

That mixer does work for alsa without pulse, but is there a way to replace the system tray volume control applet, so you don't have to use the window? Also, what about keyboard volume media keys?

""is there a way to replace the system tray volume control applet?"

sudo apt-get install xfce4-mixer

After installation, you may find it in Ubuntu Menu:

Applications -> Sound & Video -> Mixer

Catch it by mouse and move to Gnome Panel.
Then Right Click on the icon -> Lock to Panel

Other questions to Temüjin and/or Cesium

[illumilore]

Catch it by mouse and move to Gnome Panel.
Then Right Click on the icon -> Lock to Panel

That still doesn't replicate the functionality of the default gnome mixer.

[razorboy5]

is there a solution for this yet?

can't control my volume either and it's set way too soft...

edit: sry tried the mixer mentioned above now i can listen to my music at a decent level which is nice
