One-sound mixing on Ubuntu Linux

Hi everyone.
I'm running EDuke32 2.0.0devel r1900 on Ubuntu, (more precisely: 2.6.35-29-generic #51-Ubuntu SMP). The game runs flawlessly, I tried HiRes pack and all, no problems. EXCEPT I have this issue that makes the game completely useless for me.

Thing is, I can only hear ONE sound at once - I mean in-game sounds, not music, which seems to work independently. No matter what number of voices I have set, 8 or 96, I can only actually hear ONE. So, you must agree, this sucks donkey balls. I cannot hear monsters shooting at me from behind 'cos I'm reloading my pistol, hey, this can't be serious.

(As everyone using ubuntu after 2007) I'm using pulseaudio.

I searched the forum, and have only found one post where somebody had like 8 sounds, but he got no answer anyway; that's why I decided to register and write this. If I missed some previous posts, sorry and please redirect me.

I experienced this when I gave DNE a shot, but never the vanilla game. Unfortunately, I don't have a better idea than to blindly try out different configurations: for example, changing mixing sample rate, compiling with SDL 1.3 vs. 1.2, using a different sound backend (?)...

Yeah, I always manually remove pulseaudio and use the ALSA backend for SDL instead. Since I've never experienced anything like this, maybe it's specific to the PulseAudio backend?

I've never experienced that as an issue, and I am using Pulseaudio (on Ubuntu 11.04 with Gnome 3 to be informative).

If you killall pulseaudio (or pulseaudio -k) you should fall back to ALSA unless pulseaudio is set to auto-respawn (which can be adjusted in configuration files, google it since I don't recall details). See if that makes a difference.

Thanks guys. Well, it's rather not a pulseaudio-related issue. I stopped it, killed it - to be sure, I even removed it, making my system relay on alsa. Still, the game acted in exactly identical manner - one sound at once. (Actually, without pulse, it was even worse, 'cos the playback became cpu-heavy).

For now, I think I will just test some other (older) eduke versions, maybe devs made it loose some compatibility I need along the way. I think there should be some in-game mixer, which only creates one pulse/oss/esd/whatever client, so that actually it should work whatever linux soundsystem is in use. After all, it was possible in DOS:)
Utill success, I stick to my dosbox and classic duke:) It does at least 16 voices at once;)

Did you self-compile or is it packaged?

That's actually exactly what it does. This breakage is some kind of recent regression.

Edit: a regression that I can't seem to reproduce, at that.

Hi!
I'm having exactly the same problem.

Running Ubuntu 11.04
(2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux).

I use the apt.duke4.net repository for installation.

With version 2.0.0devel.20110425.r1872-1 the sound works fine,
with version 2.0.0devel.20110529.r1900-1 the bug is there.
So the regression must be somewhere between those revisions.

Maybe that helps.

Oh great! So I only have to go back a month in versions:)
Yeah well, for now let's assume its ED devs' business.
As for reproducing the bug (@TX), well, ask for whatever info you need on this, my system is pretty much customised, maybe I have some unique combination of pulseaudio bugs:)

EDIT: I confirm, the older version runs perfectly normal.
