Sound used to work in chrome, basically flash. I could play google music, youtube, hulu and it was fine. I never was able to get sound working in VLC, rhythmbox and that's pretty much the only things I need sound in. Recently I have no sound at all except for when doing osstest, it plays sound just fine over my optical audio cable. I've tried toggling some settings as well as changing the sampling rate to no avail. Any help would be greatly appreciated

The OSS manual is here: https://wiki.archlinux.org/index.php/OSS

The oss package in Arch Linux is now split into two packages:

Code: Select all

oss-4.2_2006-1-i686.pkg.tar.xz
libflashsupport-oss-4.2_2006-1-i686.pkg.tar.xz 

If you do not like the sound of "fast" resampler, you may try "production quality":

Do you have PulseAudio installed?

[KJee85]

I do not have Pulseaudio, will that even help sound to play in all applications? I'm pretty sure I have the libflash support but I'll try to grab that. I installed OSS following the manual and used to when attempting to make each of the applications work.

Update: Installed libflashsupport restarted and it works!

It is advisable to remove PulseAudio and libpulse.

Do you have libpulse installed?
Libpulse is a kind of trojan which may infect your multimedia packages with PulseAudio during compilation.

The Arch Linux wiki for Open Sound System mentions that it is not enough to set gstreamer-properties in case of Rhythmbox and Totem there is a workaround. Although I'm on Ubuntu 11.10 and I didn't need to do any workarounds for Totem, Banshee (I don't have Rhythmbox installed) to get sound.

In VLC you should have UNIX OSS as an option of the sound backend.

Does 'osstest -V' play anything? Does it play on both pcms? Also, you need libflashsupport for flash..

It seems that Arch developers compiled VLC without OSS support.
It is said that this problem was already fixed with the last update (2012-02-19)

In any case, it makes sense to recompile all multimedia packages to remove PulseALSA and other crap.

It looks like oss is in vlc 2.0 disabled by default. https://bbs.archlinux.org/viewtopic.php ... 6#p1060036

It does not seem to be true. However, if OSS is not installed, VLC is likely to be compiled without OSS support.
The same trouble can happen with MPlayer and some other multimedia packages.
If "libpulse" is installed, a multimedia package is likely to be compiled with PulseAudio (it is not always possible to disable it with configure options).

"libpulse" can be easily removed:

Code: Select all

$ sudo pacman -Rdd libpulse

You may also want to remove some other libraries (e.g. libsamplerate) before re-compiling your multimedia packages.
