I have a USB sound card for my pi b+ which I want to setup as my default sound device and all the tutorials for setting up involve editing the alsa-base.conf file in /etc/modeprobe.d, but I don't seem to have that file! Anyone able to help? I can see the usb fine when i run lsusb, and alsamixer detects it and plays audio fine. I'm running raspbian Jessie.

This is the USB sound card I'm using:

Turns out the file is now called alsa.conf and is found in /usr/share/alsa. Changed the lines

defaults.ctl.card 0
defaults.pcm.card 0

to card 1 and that's me up and running. Looks like others have different problems with other sound cards so worth looking at other solutions too. Found some good suggestions (including my solution) here:
