I have been looking through Arch"s forums too and I glad you came across this because it fixed it! So here is what I did:
From Terminal:
aplay -lIt will show you something like this:
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Headset [Creative USB Headset], device 0: USB Audio [USB Audio]
Subdevices: 0/1
Subdevice #0: subdevice #0Ok so "card 0" is my "HDMI Sound" and "card 1" is my "Creative USB Sound". Keep note of your card list!
Next you need to create a text file and name it ".asoundrc" with out the quotes. Inside this new text file add the following code:
pcm.!default {
type hw
card 2
device 0
}
ctl.!default {
type hw
card 2
device 0
}Now you need to edit the file with your correct card# to match the card you want to use. Here is an example of mine:
pcm.!default {
type hw
card 1
device 0
}
ctl.!default {
type hw
card 1
device 0
}See how I have card 1 listed. That matches my aplay -l output from above for my Creative USB Headset.
After you have edited your file save it to your Home directory. You will get a warning that the file will be hidden. Click ok and then reboot. Now you should have play back in Firefox. Hope this works for you! Thanks to Just19 for the Help!
