X220 Tablet - Windows Media Player Lags while using onenote

Hey all,

I was wondering if anyone had audio lag issues when using onenote (or the x220 in general). By lag I mean that machine-gun effect (when the audio in the buffer gets repeated over and over until new audio gets put into the buffer.. sort of like the sound you hear when your PC bluescreens if you're playing music at the time). It only happens for about half a second, but its extremely noticeable and seems to happen frequently.

I have a suspicion that it might be caused by the throttling issue plauging this laptop, but that's just a suspicion (yea I have an i7). It only seems to happen when I use the laptop in tablet mode with onenote though... (either that.. or it only happens when using headphones, as when its not in tablet mode its connected via displayport to a TV and I never have lag issues there).

Thoughts anyone? If nobody has any solutions/thoughts I'll probably find a spare disk to do a clean install of W7 on at the end of the week to double check.. half of me thinks that its Lenovo's crapware too :/

 

It's not because of the Thinkpad Active Protection, is it?
(stops the hard drive when the laptop is tilted or dropped)

 

Don't think so.. shouldn't WMP buffer more of the song than just the next 10 seconds..? Also I'm using this on a table (doing math homework in onenote) so the physical writing on the screen shouldn't contribute any more vibration than typing on the keyboard would.. shouldn't trigger the AP system should it?

 

I can't say that I have any idea how much WMP buffers.

It probably isn't the AP system then. I think it requires quite a bit of tilt to activate.

Is the screen rotated? If so, does the issue occur when the screen isn't rotated?

 

Upgrade to the latest BIOS, Power Manager, Power Manager Driver, and Audio driver. I use to have random stutter on my X120e and the problem is solve with a BIOS upgrade from Lenovo.

It is not the AP system, when AP system is active the audio does not stutter, but rather get cut off.

 

Sigh. Upgrading BIOS would break my current WLAN card.. :S I guess I'm SOL until someone hacks the newer x220 BIOSes.. but seeing how Lenovo has been releasing several trying to hammer out that throttling problem.. i dunno -_-;

(I'm using 1.11 BIOS because the 6205 does not play nicely with my access point for some reason. Using the hacked 1.11 BIOS and my Killer 1102N wifi card has had no problems).

Edit: Strange.. ICE has apparently seized the domain that the modder doing the x220 BIOS mods was using.. what the heck? Damn government and its incompetent agencies...

 

Hm too bad. Did you try any other media players? (Media Player Classic, VLC,...)

 

Not yet.. though I would imagine that an i7 w/ 8GB of ram should easily be able to handle WMP and onenote..... its not that I have a particular preference for WMP.. I just find it annoying that I would need to go digging around for solutions to thing that shouldn't be problems...
