USB Audio (no sound)

I am unable to get my USB speakers to work with my fresh install of Arch.  I have switched from ubuntu and got everything else working.  I just can't seem to get my speakers working.

I followed the beginners guide to Arch initially.  The USB speakers did not work after the install.  I then proceeded to try the steps on installing PulseAudio.  It still does not work.

The sound is not muted and it appears to recognize the USB speakers are attached, but I get no sound.

[steven@steven-arch ~]$ lsmod |grep '^snd' | column -t
snd_usb_audio       106304  0
snd_usb_lib         20672   1   snd_usb_audio

snd_page_alloc      10832   2   snd_hda_intel,snd_pcm

I certainly could have compounded my initial issue with a conflict between alsa and pulseaudio...  In any case, what can I do know?

Thanks in advance,
Steven

Re: USB Audio (no sound)

Looks like you now have two sound cards. Try temporarily disabling your internal sound card in the BIOS or by blacklisting snd_hda_intel then try speaker-test -Dsurround51:default -c6 -twav (that's the command I use to test by 5.1 speakers attached to my USB 8 channel sound card).

Are you sure you unmuted the correct card in alsamixer (F6)?

Re: USB Audio (no sound)

I disabled the sound card in the bios and it appears to work now.  However I am not sure if it is using pulse or alsa now.  I know that sounds like a silly question, but how do I make sure which one is operational?

Re: USB Audio (no sound)

For pulse you can check using pavucontrol. Just ps -e | grep pulse wouldn't work because it may not have any outputs loaded.

If you installed pulse and didn't uninstall it, you're using it. You can not disable your internal sound card and just use both soundcards with pulse, its not too hard. Just use pavucontrol to move streams to the sound card you want, or disable the sound card in the configuration there. Easier to backtrack from that than disabling the internal soundcard via BIOS or module blacklist.
