Trying to make this work under Gentoo x64, tried few examples and none worked.
For example conswebstream gives me this :

$ ./conswebstream

Nothing happens when I press a key btw.
Looking at those messages seems like it can't find a sound card or something.
I have integrated realtek sound card, never had problems before, have no clue what's going on with this. Same happens with SimplePlayer example, I click on "Load that libraries" then in terminal I get this :

$ ./SimplePlayer

Hello.

Hum, it seems that the problem is not uos but your sound-card.

Could you try this in console ?:
speaker-test -c 2 -D default

Do you get some sound ?

And what is the result of that ?:
aplay -L

Yes, your sound-card seems ok.

Did you try /uos/examples/deviceinfos program ?
What is the result ?

Other thing, what if you change PulseAudio default sound-server for Alsa or Oss ?

I really don't want to change settings for PulseAudio or anything else for this because it's working just fine as it is, doesn't matter, was just curious and had to ask, thanks for your help.

Hello.

OK, sorry that I could not help.

It seems that your sound card is 7 channels (left, right, front, Center, Side, Rear and Woofer).
I have to confess that I never try it and uos was tested only for mono or stereo devices.

Hey, no problem, I just had to ask for some reason, I didn't expect anything.
btw my card has 5 channels, don't know why aplay -L gave that output saying I have 7 channels, but in sound preferences 5.1 is selected, there is no 7.1 option, and I know it's a 5 channels card.

screenshot at 2016-09-27 19-51-58

Edit: I just tried to change that selection to Stereo and try one of the example programs, but same thing happened.

btw how do you change PulseAudio default sound server ?

Hello.

Maybe you could take a look at this:

unknown-pcm-cards-pcm-rear

It propose to remove in /usr/share/alsa/alsa.conf the unrecognized pcm's.

PS: Before to do it, please do a backup of your alsa.conf.

Thanks, that seems to be the right way to solve this, after commenting out few lines I'm now left with only two problematic, they are not under PCM section in alsa.conf, I'll play with this and hopefully manage to solve it.

Right, I've managed to make it work without error messages, however I can't hear the sound from conswebstream program and other GUI programs are just saying that libs are loaded and that window just stays like that, there are no other windows, only that load library one. Here's what deviceinfos program looks like after I press "Load that library" button :

screenshot at 2016-09-28 13-49-23

As for conswebstream, the url is valid (theurl := 'http://broadcast.infomaniak.net/start-latina-high.mp3' ;) , I can hear it when I open that url in browser, there are no error messages anymore, but still I can't hear anything, sound is working fine in other apps (it's not like I've disabled something in alsa.conf I shouldn't have and there's no sound at all)

$ ./conswebstream

Never mind, I tried BASS and it's working fine.
