Hi
I'm beginning to think that it is indeed related to the mixer and whether:
1: It's on
2: It's been turned off and back on during an up cycle of the machine.
If I turn the mixer on before boot and leave it on, thus far, I've not had the issue. Last night, it crashed (when I was doing something in Photoshop) I would say just a few minutes in. I also watch videos using the sound from the mixer which are .mkv and somewhat CPU/disk intensive, and haven't once had it crash. So... I'll keep playing with it.
is this mixer just software or do you have stuff connected to a mixing board..
Professional hardware.
Allen & Heath Xone 4D. Pretty sure it's not a driver issue.
I am, however, thinking of getting a cheesy USB sound card or once again trying to get the onboard sound to work. I don't always need sound, and as you can see, it generates a lot of electricity/heat/light. Also, VLC seems to not like the fact that there is not internal sound device. MplayerOSX and my browsers have no problem.
This machine is a Shuttle SG45H7. The onboard card is a Realtek ACL888, but
I never got it working. I built this machine to work with Ableton Live so it seemed silly to even bother since I would be using hardware for sound anyway, so I gave up rather early.
