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
Thank you for reading.

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.
