Open Sound System

Hi everyone!

I recently installed a copy of Ubuntu 10.10, everything was a success except for sound inputs. Output still worked fine, with ALSA, and the default configuration. I attempted to troubleshoot, and configure ALSA to work, with no avail. So I attempted and decided to use OSS4, which was suggested here https://help.ubuntu.com/community/OpenSound after following the instructions, which I assumed would work with 10.10 as well, even though it was meant for 9.04.

The install succeeded and for about 5 minutes, I could see the input levels working correctly in ossxmix. Once closed, input and output stopped functioning.

Here are the outputs for ossmix and ossinfo -v3. Any ideas would be much appreciated! Been attempted to get this working for the last 3 days now.

Thanks in advance, again. I appreciate any suggestions or ideas, one might have.

Best,

A) "I could see the input levels working correctly in ossxmix" I'm not sure it was the card. Does actual recording work if it's open? And how did you test recording? I suggest testing with the oss supplied util - e.g. 'ossrecord - | ossplay -' (and see if you can get an echo).

B) Trying changing recording.select... comboboxes in ossxmix to int-mic values and retest recording.

Is there a new version for UBUNTU?

i got much information about from it. How should i use the cards for ALSA? what will be the sampling rate?

Do you want to learn ALSA?
You may ask for help on the Russian Ubuntu forum http://forum.ubuntu.ru/index.php?topic=112480.0
arateconf - ALSA configuration tool (made in Russia) http://forum.ubuntu.ru/index.php?topic= ... #msg939449
fftrate is the Russian "scientific resampler" (it is said to be very exact).

You may also try to find ALSA forums (if it is not deprecated), or try to subscribe to the Russian Ubuntu forum as a "foreign guest".

This forum has nothing to do with ALSA, it is the OSS4 support forum

Thanks for your information. I will go through all those things.
