Open Sound System

Posted: **Fri Apr 02, 2010 7:02 pm**

Hey Guys, I remember you helping me out with my OSS installation. Thanks for that.

I've gotten myself into another issue though.
Everything was working fine, but one day after a simple restart everything stopped.
Totem stays on silent, Rhythmbox, requires 'gstreamer element autoaudiosinc' all of the sudden and Ossxmix is dead during any operation, though all the volumes are maxed.

Could you please help me out?

I've tried to solve the 'gstreamer element autoaudiosinc' error, bu the conventional solution doesn't work.
Also, when I go to 'gstreamer-properties' and test both of the pipelines with osssinc and osssrc i get:

Code: Select all

Error running pipeline 'OSS - Open Sound System': Could not open audio device for playback. [gstosssink.c(417): gst_oss_sink_open (): /GstPipeline:pipeline0/GstOssSink:osssink3:
system error: No such device or address]

Strangelly enough osstest works perfectly fine...

Here's by ossmix:

Trying installing gstreamer0.10-plugins-good and gstreamer0.10-plugins-bad packages. Either oss4sink or osssink should work then...

Posted: **Sat Apr 03, 2010 1:55 pm**

Done and done. Installed both packages. Still, the same outcome.
And the device is marked as 'Unsupported' on gstreamer-properties.
How can this happen all of the sudden?

hmm.. What does 'gst-inspect oss4' show? Also, can you post 'ossinfo -v3' output here?

It's there, the OSS sound device should be available... Try running the following command:

Code: Select all

gst-launch filesrc location=$oggfilename ! oggdemux ! vorbisdec ! audioconvert ! audioresample ! oss4sink

Of course, replace "$oggfilename" with an actual ogg filename.

Posted: **Sat Apr 03, 2010 11:38 pm**

A bit slower please... I'm far from adept.

How do i go around doing that?

Posted: **Sat Apr 03, 2010 11:45 pm**

Just type the command above, but instead of $oggfilename type an actual ogg file (not sure which exist on your system. Probably something exists at /usr/share/sounds).

Posted: **Mon Apr 05, 2010 4:52 pm**

Ah, ok I got it. Tried it...
Sadly nothing works still.
And no program that has anything to do with sound works, Rhythmbox, VLC even skype... :?:

Posted: **Mon Apr 05, 2010 4:56 pm**

Ah, so it's not just a gstreamer problem... I thought the rest worked.. Does "osstest" emit sound? If so, does "osstest -V" work?

Posted: **Mon Apr 05, 2010 5:03 pm**

Osstest does emit sound, which is scary after several days of silence from my computer, but then it also comes out with this:

weird... I noticed that your OSS is a bit old (build 2000 while current is build 2002). Perhaps you can try to upgrade it to latest version?

Posted: **Tue Apr 06, 2010 1:49 pm**

I know, weirds me out. How do I upgrade it again?
The Package manager indicates the the 2000 version is the latest, which is obviously not the case.

Go to 4front.com, select "Download", click on "Open Sound System" graphic, and then select "Linux 2.6 (x86) DEB" in the drop down. Click on "Submit" and download the deb. Once you have downloaded it, do "sudo dpkg -i oss-linux-4.2-2002_i386.deb" to install the new deb.

Thanks for the baby steps! I don't really know how or why, but it seems to have worked.
