If ossinfo and ossmix fail to produce any result, you have to remove OSS and reboot.
Then you may try to install OSS correctly. The manual is here:
https://wiki.archlinux.org/index.php/OSS

If you do not know how to remove OSS, you may read this:
viewtopic.php?f=3&t=3543&start=30#p15711

In a word, OSS seems to work on Arch Linux with kernel 3.0 without problems.
It seems to be the same old kernel, only the name is different, a kind of "Potemkin village" http://en.wikipedia.org/wiki/Potemkin_village

[xirotyu]

actually i tried ossinfo and ossmix with a script like this

Code: Select all

#used to start oss on archlinux
rc.d start oss

#script to grab the log
ossinfo > ossinfolog
ossmix > ossmixlog


i use the script because the noise is heard when i start the oss.
if i try type the ossinfo to the terminal it shown up but after that, the laptop just freeze, with the usual loud noise...

You are doing something very strange with your Arch Linux.

Do you mean the "Blue Screen of Death"? http://en.wikipedia.org/wiki/Blue_Screen_of_Death
Is it really Arch Linux, or it is a kind of M$ Windows?

Does your ALSA works?
http://www.google.com/search?hl=en-US&q ... %204200%5D

You may test ALSA and OSS4 with Arch LiveCD, the manual is here: viewtopic.php?f=3&t=4387

but the sound is..... freaking loud i just cant stand it, and i dont want to broke my internal speaker.... maybe i have to unplug the internal speaker first.... but the warranty...

i think i have to use alsa.... without pulseaudio (rebuilding some package to disable pulse audio). maybe next time when i can grab some cd... or usb flashdrive i try the oss again

USB Audio devices are not likely to work with OSS4. You have to know this, if you read the OSS4 manual in Arch Linux Wiki. There is a special Arch Linux forum for those who do not want to read the Arch Wiki: https://bbs.archlinux.org/viewforum.php?id=23

Since ALSA driver for your soundcard does not support "hardware mixing", you may need something instead of PulseAudio, a kind of ESound, for example.
To improve sound quality with ALSA, you may want to disable the evil "linear resampler" of ALSA, see: viewtopic.php?f=3&t=4387 If you do not know, how to disable that resampler, you may ask for help on Arch Linux forum: https://bbs.archlinux.org/viewforum.php?id=23

thanks but i already read the wiki... and managed to make it work on other machine. the device is not usb device... i already list the lspci.... the audio device is listed..... read above
i have 2 audio device... one for analog, the second for hdmi. is it that raised the problem? the default for linux 3.0 radeon audio is disabled

This card should work with OSS4. This was reported on the Russian Ubuntu forum, Linux Mint forum and on this forum.
Perhaps, you have to attach vmix to it to make it default, see: https://wiki.archlinux.org/index.php/Op ... em#Testing

Code: Select all

$ man vmixctl

But where is your "ossinfo"?

Have you tried to re-install OSS4?
Sometimes it helps to recompile OSS4 (for your particular Linux kernel), see: viewtopic.php?f=3&t=3543&start=30#p15711

https://wiki.archlinux.org/index.php/Op ... io_devices
You'll probably want to setup a program to record/play continously in the background (e.g. ossrecord - for recording or osstest -lV for playing), while changing mixer settings in ossxmix in the foreground.

Code: Select all

$ ossrecord -vl - | ossplay -
Recording wav: Speed 48000Hz 16 bits Stereo
- [.......   ] 7.00 secs VU -------++

It makes sense to test your soundcard with OSS4 on Arch LiveCD: viewtopic.php?f=3&t=3933#p17359
It should work "out of the box", I presume.

woops... solved with

viewtopic.php?f=3&t=3541

high pitched squeel..... *my english is bad
i just cant turn off the sound because its laptop internal speaker....

Good news!

Does your microphone work?

With this soundcard, you may need to fix it with "trial and error":
https://wiki.archlinux.org/index.php/Op ... io_devices

Code: Select all

$ ossrecord -vl - | ossplay -
Recording wav: Speed 48000Hz 16 bits Stereo
- [.......   ] 7.00 secs VU -------++

Do you have a simple analog microphone?

I had the same problem OSS 4.2-2005 on Ubuntu 11.04 and Realtek High Definition Audio ALC888 soundcard. Although the sound wasn't loud in my case (it was more like white noise).

I've changed the jack.blue.mode (in ossxmix) from input to rear and that noise disapeared instantly.
