Changing default sound devices in Ubuntu

[lex-ington]

I recently installed 8.10 and decided to install the ALSA 1.0.18 package myself today.

I think I got quite far as I get this in the terminal:

Code: Select all

hdmi@hdmi-desktop:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC883 Analog [ALC883 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: ALC883 Digital [ALC883 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
hdmi@hdmi-desktop:~$



When I start the alsamixer, the system is apparently set to use the [HDA ATI SB] device. I want to use the [HDA ATI HDMI] device, as ALSA is now saying they support sound over HDMI. I went into the sounds preferences and set that to HDMI, but the alsamixer is still showing the HDA device.

Does anyone know where I can change the default sound device? I have scoured the internet and haven't really found anything helpful yet.

Thanks.

You should probably delete /var/lib/alsa/asound.state and /etc/asound.state. I had to do this when I switched from onboard audio to a discrete sound card. Since you're doing more or less the same thing (moving from one sound chip to another), you need to delete the saved information in those asound.state files before running alsaconf and then setting your levels in alsamixer.
