USB Audio glitches with Riffworks - HP Pavilion dv5 Notebook

Hello,
When i start Riffworks Line6 Edition, the PODXT shows a clip (althought output + volumne are set to zero..)
If i press the PLAY button (Instant drummer comes...) i have terrible glitches. Theese are so laud, that the instant drummer or the Riffworks metronome (cow-bell) could'nt be heared. The clip is also visible at the ASIO CONTROL PANEL/Inputs & Recording - Tab. even without i press play or record.
And there are many small more silent glitches, to the Speaker of my guitar Amp, even if nothing is activated but Riffwork was started?
I've already found this:
http://line6.com/community/docs/DOC-4282
I have disabled Wireless Lan, set Accu power status to highest Level, set Audio Setup / ASIO control Panel in Riffworks to Extra Lagre - Buffer Size (USB Audio streaming), disabled HDMI Sound..
variing PODxt Monitor Level, ASIO Settings: default buffer size or bit depth, does not change anything..
Any Idea?
thanks Metalmusic
PS:
I have a brandnew HP Pavilion dv5-1112ea Notebook: 4 GB - RAM, 320 GB Harddisk,
Processor: AMD Turion X2 Ultra Dual-Core Mobile, 2.2 Ghz – ZM82 with 2MB L2 Cache,
running with ubuntu Linux 9.04 and only for Line6 i've bought & installed a dual boot Vista (SP1) 32 bit to avoid driver problems etc..
(On my Old HP-Omnibook XT 1000; 1,2 Ghz, 256 MB Ram, 20 GB HD and USB 1.1, + WinXP i never had this glitches. Only one short every 10 minutes or so..)
without a connected guitar:
If i select in the ASIO control Panel: PODXt Audion Signal Routing from: "send processed guitar" to send "clean guitar and re-amp playback" the many silent (without pressing play or record in Riffworks..) glitches from my guitar Amplifier are gone. Instead there is another white noise (lika a radio out of tune..), and the cow bell sounds very high and distorted, if i push play...
If i want to close Riffworks, the Save changes Box (would you like to save your changes? untitled) comes and there is a high noise(like the first B on the D-string at the guitar) . It is not a continuous sound, it sounds like a pulsed signal / voltage..
with a connected guitar:
there is a huge white noise with the "clean guitar and re-amp playback" setting.
On the Laptop DMA (ultra dma 5) is already enabled
(under Linux we have this: https://wiki.ubuntu.com/LaptopTestingTeam/HPDV51112ea
is there anything else for Windows? Or is there anything else i can test? )
Oh no i just found this...![]()

I do not have this problem described in there but maybe it has something to do with the genereal white noise problem.
Here's another interesting one, i'm gonna check this out
