%%%Hi,

in the bug #4512 (http://projects.blender.org/tracker/?func=detail&atid=264&aid=4512&group_id=9)
I have explained my problem with audio in the Sequencer Editor with Blender 2.41.

Now with the last version of Blender 2.42 I have a strange situation.

Case 1:
I use a Dell Inspiron laptop with ATI graphic card and an Intel Audio card and Ubuntu Dapper OS installed. If I run blender with the "-g noaudio" option I can ear the sound in video Sequencer Editor. Starting blender without this option the result is no audio.

Case 2:
I use a Hp Compaq nw9440 laptop with Nvidia graphic card and an Intel Audio card and Ubuntu Dapper OS installed. If I run blender with or without the "-g noaudio" option I can't ear the sound in video Sequencer Editor. No way to ear the sound.

Both laptop have installed the same Linux OS Distro with same update level. Both laptop use the same blender package downloaded from blender site.
In other words: same conditions, but different result.

I have tried all the possibilities on my HP laptop, but the message in the console window is always the same:
"Couldn't open audio: No available audio device"

Our sound system is a mystery for nearly all our developers. We need someone to adopt this orphan!
I don't know a coder to assign this to even... will ask around in the mailing list.%%%

Thank's Ton,

Blender is now a very powerful tool for us Linux users. It is a 3D graphical tool, a Game Engine, and finally a Video Editor with FFMPEG.
All parts of Blender are always recoded, debugged, and became more and more better: the only one exception is the sound system.
For us Linux user this is a big problem. Now that FFMPEG is arrived I can't edit my video clips because I can't ear the audio.

I have readed around in different forums (Blenderartists, Blender.it, ...) and always I meet other Linux users with this same problem.

If you find a coder that can review the entire sound system, for us Linux users this will be a very big present!%%%

I had the same prob on ubuntu dapper. I fixed it by recompiling SDL manually.

Here's my configure string for SDL:
./configure --prefix=/usr --with-gnu-ld --with-pic --enable-video-opengl --enable-dga --enable-alsa --enable-cdrom

this can be fixed by installing (if it's not already) the libsdl1.2debian-all
then
export SDL_AUDIODRIVER=esd
and lastly disable blender gameengine sound (I did this both in the user preferences and by the flag -g noaudio)
it seems like blender sound engine likes to get the dsp to itself otherwise, and somehow it can't get it otherwise (under ubuntu)
other solution is to get a sound card with built in hardware mixing... these are getting rarer and rarer these days.

Every other package I've tried on this system that is supposed to have sound works just fine. Some examples of apps that have sound working fine: Pitivi, Ardour, Audacious, Flash inside Firefox.

Any clues for me? I'm somewhat frustrated since I have no errors. Just no working sound.

(I have also tried selecting the sound clip, then creating a FAC curve at constant value of 1.0, thinking that might be it).
