First of all ts3 client beta was a great release.
No problems at all.
But the X-fi alsa driver has a bit low mic capture mixer setting.
In ts3 I am 20-30 db lower than the windows 7 version.
So maybe you can make a hotfix for the creative X-fi alsa sound driver on linux.
The ts3 version can check the sound module if it is the X-fi sound card module the software voice amplification can be 20 db or 30 db higher than normal.
That helps all X-fi users on the linux os.

Thank you.
