I can't seem to get any sound working on BT4 PF (it used to work fine on the beta). I have a creative X-Fi Titanium Fatal1ty Pro Series card and to install the drivers I first do a:

lspci -v
Code:
03:00.0 Audio device: Creative Labs X-Fi Titanium series [EMU20k2] (rev 03)
        Subsystem: Creative Labs Device 0043
        Flags: bus master, fast devsel, latency 0, IRQ 18
        Memory at fe7f0000 (64-bit, non-prefetchable) [size=64K]
        Memory at fe400000 (64-bit, non-prefetchable) [size=2M]
        Memory at f8000000 (64-bit, non-prefetchable) [size=64M]
        Capabilities: <access denied>
        Kernel driver in use: CTALSA
        Kernel modules: ctxfi

01:00.1 Audio device: ATI Technologies Inc HD48x0 audio
        Subsystem: ATI Technologies Inc HD48x0 audio
        Flags: bus master, fast devsel, latency 0, IRQ 17
        Memory at f7efc000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: HDA Intel
        Kernel modules: snd-hda-intel
and look at the the device number (in this case 0043) so i download the driver code from the creative site and in the ctdrv.h file, change the PCI_SUBSYS_CREATIVE_SB0880 macro to 0x0043, and then issue:

Code:
make
sudo make install
This method works perfectly on Ubuntu (8.04, 8.10, 9.04) and Linux Mint (7) system and I remember it working on BT4 Beta. But on the PF im not getting anything. When I open KMix it won't let me chose from ANY mixers, not even the mobo one for which I had never had to install any drivers for. Any help is appreciated thanks.
