Those seem to be correct ..... just confirm that
/etc/alternatives/soundprofileis a link ....... right click on it and select 'Properties' ..... it should have an entry that reads
Points to: /etc/sound/profiles/pulseIf that is there then it is correct.

It would be best if you could use speakers or headset directly rather than the wireless headset ..... but I don't really suspect the wireless unit if it works normally with another OS.

I am back to wondering about the sound card and whether it needs a later kernel for support.
There is a 3.4.11 kernel in the testing section of the repository, and it might be worthwhile installing that kernel to see if it makes any difference.
To do so you would need to add
testing to the sections of the repository you use in Synaptic
main updates nonfree kde games testing Then Reload and search for
kernel-3.4.11-pclos1.bfs and install it.
It will bring in one other kernel package.
After install reboot and check that you are using the new kernel with
uname -r Test the audio with the new kernel.
If you do not wish to keep that kernel you can boot using the older one and then uninstall the newer one.
Do not attempt to uninstall a kernel that is presently in use

It would also be advisable to use more than one application to test the audio ..... play an audio file with a player app as well as what you have been testing with.
