Major Linux sound bugs

Major Linux sound bugs

[turbolad995]

Hi. I don't know who to contact about this, but nobody seems to know 
how to fix this problem or where/why it's occurring.  Here's the 
lowdown: in Linux distributions such as Ubuntu, some programs will 
only work with sound when you close ALL other programs first. I've 
mentioned this on Launchpad, but nobody seems to know why or how to 
fix it. 

Thank you for reading.

Thats usually youtube or something, hogging the sounddriver I think.

Sound arbitration is pretty much entirely done in user space. You need to
talk to your distribution about it and how the software it uses is
configured. Probably some of what is shipped is not configured to share
nicely or you've added something which doesn't play nice.

This isn't a kernel issue. Usually this is due to those programs 
incorrectly accessing device-specific ALSA devices like "hw:0", etc. 
rather than just using the "default" PCM device. Doing this bypasses 
software mixing and requires exclusive access to the sound device.
