I don`t use LXDE in Lubuntu. Use Debian Testing based AntiX 11.

Try typing in terminal

Code: Select all
alsamixer


Hit the f5 key and make sure speakers and other sound controls are not muted or turned up.

To unmute, Use the m key on keyboard.

thanks for the reply, but it didnt seem to change it.
i booted another distro off a live cd and got sound, so i can rule out a hardware problem.

could it have to do with that im using 32bit? and not 64?

No. 32bit will run on 64bit systems. So I don't think that had anything to do with it.

Might have more to do with the Kernel than anything else. Might be using a different release of alsa also maybe.

Try this: Go to System Tools, Users and Groups, and make sure that Audio Devices are enabled for your account. By default, this was disabled on my install. And I also had to go to Synaptic and uninstall Pulse. I think Pulse conflicts with Alsa. Good luck.

Hi. I'm having this exact same problem.

The solution posted by denflen didn't work. (pulse package was not installed. I uninstalled libpulse0 but it didn't work either.)

Here's the output of lshw -c sound:

Code: Select all
PCI (sysfs) 
  *-multimedia:0         
       description: Audio device
       product: Wrestler HDMI Audio [Radeon HD 6250/6310]

       physical id: 1.1
       bus info: pci@0000:00:01.1

       configuration: driver=snd_hda_intel latency=64
       resources: irq:16 memory:90240000-90243fff


Notes:
- I have checked codec compatibility in https://wiki.ubuntu.com/Audio/HDAGeneric. It is supported.
- I have checked that everything is correct in the alsamixer, following these instructions: https://wiki.ubuntu.com/Audio/Alsamixer
- linux-alsa-driver-modules does not show up in Synaptic after adding ppa:ubuntu-audio-dev/ppa. apt-get install linux-alsa-driver-modules-$(uname -r) also did not had results. This was according to https://wiki.ubuntu.com/Audio/Installin ... verModules
-
Code: Select all
$ lspci | grep Audio

Shows:
Code: Select all
00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Wrestler HDMI Audio [Radeon HD 6250/6310]
00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40)

Be sure that pavucontrol, pulseaudio, pulseaudio-utils and libgtk-3-0 are all installed. Then play with the different settings in pulseaudio volume control and the controls in your player until you get sound. http://douwil7.100webspace.net/linux/Tuning.html#17
