USB audio problem [ SOLVED ]

natgab · 2012-07-03 23:36:24

new #! user here,

I have a USB audio card (see info below) and chose it in ALSA mixer, and still don't get sound. I looked around and found USB audio threads but most are about #! not finding the USB audio, but mine sees it.

I just can't figure out what setting to use for sound. I've previously used Ubuntu, and that finds my usb audio and works. I set channel preferences in ALSA to master but still don't get sound.

Yes my MB audio works, but since I need to use the iMic for OS X I don't want to be swaping out the wire everytime I reboot.

Hackintosh specs:

GIGABYTE GA-G41-ES2L Micro ATX
Intel G41 Northbridge / Intel ICH7 Southbridge / Intel GMA X4500 video
Realtek ALC888B audio / Realtek 8111DL nic / Griffin iMic USB Audio

Intel Pentium E6300 Wolfdale Dual-Core 2.8GHz LGA 775 
Crucial 4GB SDRAM DDR 800 (PC2 6400)
GIGABYTE GV-N84S-512I GeForce 8400 GS 512MB PCI Express 2.0 x16
SYBA PCI USB 2.0 & 1394a combo card
LITE-ON CD/DVD Burner bulk SATA OEM 

OS X 10.7.4 / 10.6.8 / #! 10 Statler / Haiku alpha r3 / Windows XP

Tried again today and still no sound. OS X & Win XP see USB audio fine.

It's a common misconception that you can actually select your default audio output device in alsamixer. The mixer app that ubuntu uses is called pavucontrol and the reason it is capable of doing that is because it uses a pulseaudio server. The plain old ALSA configuration found in #! statler is a bit more bare bones, so you need to create a config file that tells it what card to use, otherwise it just defaults to card 0 which will usually be a sound device on your motherboard or hdmi video card if you have one. For now, try adding a file named .asoundrc to your user's home directory and put this in it:

 pcm.!default {
      type hw
      card 1
      device 0
 }

Then you need to either restart the whole computer, or just restart ALSA like this:

sudo service alsa-utils stop
sudo alsa force-reload
sudo service alsa-utils start

It's possible we may have to edit asound.conf or something to enable usb devices as the default audio device but just try that for now and see what happens.

Worked perfect. Just had to go and open File Manager in root to make sure I put the file in the right spot. Thanks! ( now off to see what I need to tweak on my Laptop )
