Hi everyone. For some strange reason, KDE and pulse audio (together) crash my system. This has happened with several distros, so I am using Gentoo to avoid having pulse audio on my system.
I have tried to follow the ALSA guide on the wiki, but I can't seem to understand how to get my two sound cards configured so that the USB is the default, and they make sound.
Here is the output from aplay -l
Code: | chris@GentooStudio /etc/modprobe.d $ sudo aplay -l

I run alsamixer, and it shows "Internal Validity" under the 2i4, but is green, so therefore unmutted, I assume. The daemon is running, but no audio is going to the default HDMI port from chrome, or how to switch the default to the second card. I had the ALSA USE flag set when everything was built.
Any suggestions?
Thanks,
Chris
