Total noob. Please help.

Hi guys,

I'm an audio guy who works mosly in Mac and Windows however I do enjoy Ubuntu Studio (I have Harrison Mixbus and can operate Ardour) because of all the awesome applications it comes with for all sorts of production.

I have been trying to get my Lynx AES16e to work and I stumbled upon OSS. I purchased a license and am currently awaiting a key for the retail version, which according to the documentation, supports the AES16e. I have a few questions:

1. How do I inject my key (when I receive it) into OSS to activate the Professional Audio mode (Lynx support)?
2. Does OSS work with Ardour? In other words, can I record low-latency multi-channel audio with it?
3. Can anyone point me to a general tutorial or overview of how to use OSS?

Thanks for your help in advance.

Cheers :)

Two pages which hopefully you have already read before purchasing a commercial license:

http://manuals.opensound.com/devlists/lynxtwo.html
http://www.opensound.com/license.html

These should have answered your first question.
Before asking does Ardour work with OSS you should check whether OSS works with your sound card using osstest and ossplay which come bundled with the drivers.
Regarding question three, have you consulted the OSS wiki?

Thanks, yes, I have read the links you provided and after some tinkering I am able to get sound output via osstest, so the card is recognised and working. I am able to get sound from Audacious by playing a file, however it is very soft and I am unable to change the volume. The master system volume control is not linked. ossxmix shows output but still, the sound is very, very low. Either way, $10 is not a lot of money and I figured I may as well give it a try if I can get multichannel support in Ubuntu with my AES16e.

Everything seems to be detected correctly but I am having trouble setting OSS as the default sound device. I edited the soundon.user, osscore.conf, device_drivers (I think) and other configuration files as per the wiki instructions but to no avail. I also disabled my on-board audio.

Is there anyone that can walk me step by step through this so that I can use OSS as my default sound device? Like I said I am a relative noob to Linux but I learn quickly so please help!

Thanks again.

Cheers :)

This forum does not support "closed-source" drivers.

If OSS4 is correctly installed, and your sound card is supported, it should not be difficult to set proper "sound output volume" through the help of OSS Mixer GUI (ossxmix).

Guys, I'm getting the feeling of an air of condescension here which is translating as unhelpfulness. While I am a noob at Linux/Ubuntu, I am not computer illiterate and I can "get" the ideas behind its operation so would it kill you guys to be a little friendlier?

In regards to the "closed source" comment, I am not currently using the retail version as I have not yet been sent my key. So, thus, I am using the open source version. This is curious because I was under the impression that Lynx hardware was only supported in the retail version. When I run osstest I get a clean, clear signal in all tested outputs (there are eight stereo pairs). I did try to use OSS in Ardour (it is selectable) yet the program reported that it was unable to connect to the audio engine.

And yes, ossxmix is showing output but it is not easy to adjust, as you say. The volume control is at 0dBfs (full scale) yet the output from Audacious is very low. Adjusting the volume on Audacious does nothing, nor does adjusting the Gnome volume control on the task bar.

I will check out the link you shared. Thank you.

Cheers :)

There are no open source drivers for Lynx soundcards for any operating system as the manufacturer will only provide interface specs. under a none disclosure agreement. You are probably using a version of the commercial software operating with a demo licence.
If you could post the output of:

Code: Select all

ossinfo |head
we will be able to see what version of OSS you are using.

Code: Select all

lsmod |grep oss
will also show which OSS kernel modules have been loaded.

You say the output of osstest is crisp and clear but you do not give any indication as to whether the volume is acceptable.
Could you also play a .wav file using ossplay to check on volume and fidelity,
While there isn't any mention of Ardour in the wiki I believe it uses JACK for sound output so you may like to read up on using JACK with OSS.

I do not have a Lynx soundcard so am unable to check its operation with OSS.
While there have been other contributors who use these soundcards posting in the past I am not aware of any (other than yourself) who currently read this forum.
I hope someone will prove me wrong.
regards

Clive
