If you have more than one card in your system, or precisely, than the system see more than one card (one sound card and a usb camera with a microphone for example), you must define which one is the default one. Here are the steps to achieve this:
Firstly, determine the name of your sound card:
cat /proc/asound/cards
The name of your card is in the brackets. For me:
0 [U0x46d0x9a4 ]: USB-Audio - USB Device 0x46d:0x9a4
USB Device 0x46d:0x9a4 at usb-0000:00:10.3-1, full speed
1 [VT82xx ]: HDA-Intel - HDA VIA VT82xx
HDA VIA VT82xx at 0xfbffc000 irq 17
The one I want to make it default is VT82xx
Then add the following file /etc/profile.d/alsa.sh with this content:
#!/bin/sh default_alsa_card=VT82xx export ALSA_CARD=$default_alsa_card export ALSA_PCM_CARD=$default_alsa_card export ALSA_CTL_CARD=$default_alsa_card
Of couse, replace VT82xx with your sound card name.
Make this file executable with:
chmod +x /etc/profile.d/alsa.sh
If you want to have it works immediately, source that file with source /etc/profile.d/alsa.sh and run your audio applications from this terminal or simply reboot.
