USB audio issues with Clover

[Rage-]

Hello.

My PC is:
Corei7-860/8Gb/Gigabyte GA-H55M-USB3 (non-EFI BIOS )/Geforce GT 240/USB Audio ProDigy CUBE 24/96. I'm running clover v3333.

I never had any issues with my USB sound card with Chameleon (Chimaera) bootloader + DSDT from Tonymac. It worked like a charm out of box since 2010 (OS X 10.6).
Now I moved to Clover and started to experience audio issues.

When I start to play music (watch videos) it works nice, but after 2-3 minutes after playing, suddenly sound speed slowing down a bit and getting choppy (like 64 kbps MP3 comparing to 364 kbps).
I guess, it might be somehow related to USB tweaks issues, which i can't figure out.

I'm using such USB-related tweaks for now:

<key>FixUSB_1000</key>
<true/>

<key>USB</key>
<dict>
<key>Inject</key>
<true/>
<key>FixOwnership</key>
<true/>
<key>AddClockID</key>
<true>
</dict>

I attached my config.plist there.

Also I've tried to use DSDT.aml which I successfully used with Chameleon (placed in ACPI\patched). With no success I might add.

Any advices about further investigation for this issue, please?
