Sound on Gnome [solved]

Message

Hey there guys, wonder if any of you can help!

I have problems getting sound to work in gnome.

I have configured alsa, everything is apparently ok (cat /dev/urandom > /dev/dsp gives the static as mentioned in the ALSA guide), however I am getting nothing from sound in gnome. I have tried to test sounds from the gnome sound preferences, but get nothing. Any suggestions?

Cheers

Im having the same sort of problem (see my last post "Choppy sound in Gnome")

What sound card are you using?

Let me know if you find out anything useful!

It's an onboard nVidia nForce3 250Gb AC'97 audio controller

Thats exactly the same as mine.

OOS works, but the sound makes a loud click when I start/resume playing a file.

I think there maybe some settings in ~/.asound that need changing.

May I ask how you set OSS?

Just using "multimedia systems selector" in gnome.

Hmmmm, testing ALSA gives me an output, still no sounds in gnome though!

Same problem here with the exact same chipset.

i think you might have to set something in gconf -> system -> gstreamer -> 0.8

?

If your having the same problem as I was having all the information you need is here:

http://gentoo-wiki.com/HOWTO_ALSA_sound_mixer_aka_dmix

In short though, you need to create this file "~/.asoundrc"

and put this in it:

pcm.nforce-hw {
type hw
card 0
}
pcm.!default {
type plug
slave.pcm "nforce"
}
pcm.nforce {
type dmix
ipc_key 1234
ipc_perm 0660
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 4096
#rate 44100
rate 48000
}
}
ctl.nforce-hw {
type hw
card 0
}

Now, Emerge gnome-media (if its not already), go into configuration editor (gstreamer-properties) and set Audio-Sink's in System/GStreamer/8.0/Default
value to alsasink device=dmix

Hope this helps somebody.....

MannyCalavera: NO! Alsa has dmix enabled and functioning by default with no .asoundrc since 1.0.9. This is not the problem.
Also, in the config you posted, you have made the default pcm be dmixed and didn't specify a pcm named "dmix", if you set the device in gstreamer to "dmix", it will just use the dmix plug-in with default options, not the dmixed device you created. To use that you have to set the device to "default".

Reiver Fluffi: To enable OSS emulation in ALSA, you have to emerge alsa-driver with the OSS use-flag set. Since you have a /dev/dsp, which is the OSS device, you also have OSS emulation. Btw, if you want to test ALSA playback, use

Code: Select all

cat /dev/urandom | aplay

Using

Code: Select all

cat /dev/urandom > /dev/dsp

tests OSS playback. If, however, you have ALSA, this will go through the OSS emulation layer and then be output normally by ALSA. One more thing - even though dmix is enabled by default, it does not work for apps using OSS. To use those, you have to stop all sound-producing programs and then start the app, or buy a SoundCard, that can do hardware mixing. Alternatively, you can use aoss, which works with almost all apps (mmaping support is a bit buggy). To start an OSS app through aoss, use

Code: Select all

aoss <app> <app arguments, if any>

Do not type the less-than and greater-than brackets.

Oh, and what do you mean by "Sounds don't work in GNOME"? Do you mean that you cannot listen to music, etc or do you mean that you cannot hear sounds from GNOME when you log-in, etc?

Yeah that's what I am meaning. Even when I try to test the sound.

From terminal I use cat /dev/urandom > /dev/dsp, this gives me an output.

From gnome:

Desktop Menu>Multimedia Systems Systems: I get output when testing ALSA, but I get a "no pipeline" error when testing playback on OSS!
Desktop Menu>Sound: When I try to play any of the event sounds (wav) in the list, I get nothing.

Do you have "esd" in your USE flags? Gnome system sounds wont work without it.

I haven't added any flags as such. All I can tell you is that I used a stage3 install for i686 and genkernel, not sure what the default flags are in make.default (didn't know much about the flags and make.defaults file until today (after some reading). If the gnome and GTK flags are present in make.defaults, would it be right to assume that esd would be there as well? Not at home at the moment, so I can't get access at the moment.

Cheers

Solution to this is quite easy.

1 edit /etc/make.conf and add esd to the USE flags.
2 re-emerge gnome-session and libgnome
3 Go to Desktop -> Preferences -> Sound and thick "Enable soundserver at startup" and "Sound for events"
4 Restart gnome and you should hear sound

Will give it a go tonight!

Had the same problem of no system sounds in Gnome.
Re-emergeing 'gnome-session libgnome' with the 'esd' USE flag corrected the problem.
Many thanks.

esd is already in use.defaults and has been used for compiling already, here is output from emerge --info:

fredor · Post by **fredor** » Thu Nov 17, 2005 7:56 pm

I had the 'esd' USE flag but somehow it hadn't been used in the compiling of 'gnome-session' and 'gnomelib'.
I suggest you re-emerge them.
After doing that I had to run 'ldconfig' to correct a library problem.

Reiver Fluffi · Post by **Reiver Fluffi** » Thu Nov 17, 2005 8:45 pm

Tried this and it worked:

Code: Select all

USE="esp" emerge gnome-session libgnome

However I emerged it again without declaring the use flag, still get sound! (although I had to emerge gnome-audio to get some of the sounds).

Cheers
