Slackware 14.0 and Multiple Sound Cards

So this blog is mostly a place for me to keep notes on particularly annoying problems that were solved after a fair bit of pain.

So my current desktop set up has three sound devices. There is the onboard sound card, there is the hdmi output from my NVidia graphics card, and then theres the PCI Xonar DS card I bought recently.

Which is where the problem started.. I wanted to get the sound to work through only through the PCI sound card, but whenever the computer booted, it was a total dice roll on which card ALSA deemed the default audio device.

Enter /etc/asound.conf. After a fair bit of fiddling I managed to get the audio through the PCI card every boot, but I was having annoying issues where only one application could use the sound card at a time. Then I read about dmix, which solved that problem.. Then my microphone wouldn't work.. Enter 'dsnooped'.. Which somehow meant my microphone worked, but returned me to only being able to use one sound application at a time..

Thankfully I managed to find a blog post with a simple solution. Adding a file to /etc/modprobe.d/ called 'snd_virtuoso.conf' with the following one liner..
options snd slot=snd_virtuoso,snd_hda_intel
Which lets modprobe.d know which order I'd like my sound devices initialized. Delete the monstrosity that is the /etc/asound.conf and rebooted.. Everything is working as intended now
