Open Sound System

Posted: **Fri Aug 09, 2013 3:53 pm**

I would really appreciate if someone could help me with this. I've been trying to get some sound of my LynxTwo-C for quite some time now...it's been working fine until I reinstalled the OS.
Nothing wrong with the card, it still works in Windows.
So, what I have is Linux Mint 14 x64 and the oss-linux-4.2-2008_amd64 driver.
I removed pulseaudio from my system and installed the driver. Then set the VLC output to /dev/oss/oss_hdaudio0/pcm0

ossinfo output:

/dev/oss/oss_hdaudio0/pcm0 has nothing to with LynxTwo-C, it is Intel HDA codec of your motherboard.

Does "osstest" play music?

Code: Select all

$ osstest

Type on terminal:

Code: Select all

$ dmesg | grep oss

$ lspci -vnn

and post the output here (mark it as "code").

Thanks for the quick reply!
osstest playback is very faint, barely audible.

Type on terminal:

Code: Select all

$ ossxmix

It should produce mixer GUI with tabs. One of them should be for Intel HDA, other for LynxTwo.
Set proper sound output volume.
Then run osstest
It should try to play sound through all devices (of Intel HDA and of LynxTwo).

Post the output of osstest here.

See also the manual for osstest:

and manual for LynxTwo:

That worked! Thank you so much!!!
Didn't know there was a GUI control, I've been using command line controls up until now.

Could you please rename the thread as "solved"?
