No sound on debian live usb using pavucontrol and ATI RS880 [Radeon HD 4200] audio


Hello everyone.
The sound isn't working on my debian live usb.
I've installed pavucontrol hoping that this would turn on the sound somehow. But it hasn't.

The program is showing RS880 HDMI audio [Radeon HD 4200] as my output device.
The play back bar moves when I play video on youtube but there is no sound.
On the configuration tab, I've tried all the options under 'built-in audio' - but none of these seem to work.


aplay -l

Code:
 
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: ALC892 Digital [ALC892 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
Don't know why there are 3 playback devices...

lspci | grep -i audio

Code:
00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40)
01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS880 HDMI Audio [Radeon HD 4200 Series]
Not sure why there appears to be two sound cards...

On a Ubuntu site about a similar problem with the same sound card, they suggest creating /etc/asound.conf and adding code to it http://ubuntuforums.org/showthread.php?t=1647400
However, at this point, I'm a bit lost.
Can someone help please?

There is no .asoundrc file in the user account.
So I created one like in the link.

This seems to show I have two sound cards. One is HDMI.

Code:
    aplay -l
This shows 3 devices. The last one is HDMI.

Code:
     alsamixer
When I press [f6] to select a sound card, the HDMI card is showing the message 'this sound device does not have any capture copntrols'.

So I can't test the card to see if it's working. Is there a way I can add capture controls to this HDMI card?

This problem is solved from another thread, but I thought I'd update this one too.

I eventually did a search on the radeon hdmi sound card and came across a number of linux-users with the same problem.http://askubuntu.com/questions/67113...-radeon-driver

The solution is this:
Code:
# gedit /etc/default/grub
Then change the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"

Then:
Code:
# update-grub
Reboot.

Turns out the coding was removed because it would turn the screen black for some Intel users because they used the HDMI port for both sound and graphics.
So all users with an ATI RS880/Radeon 4200 hdmi sound card have to manually insert the above code.
