WMP 11 hiccups

I am running a new Dell Inspiron E1705 (Intel Core 2 Duo 2 GHz, 2G
RAM) that came with Vista Premium. Every few minutes, there is a
"hiccup" when playing MP3 files.

I ran the "Reliability and Performance Monitor" and found that when
the hiccups occur, there is a big spike in "C1 Transitions/sec." (from
zero to over 6,000) and a simultaneous dip in "C3 Transitions/sec."
from an average around 2,000 to zero. There are occasional C1 spikes
without a C3 dip and those don't seem to affect Media Player. This
would seem to indicate an issue related to CPU power states.

I am running on AC/Power in "High performance" power mode. It is set
with a minimum processor state of 100% and to never sleep or
hibernate. I also noticed a corresponding spike in the "dwm" process
CPU usage, so I disabled the Sidebar. "dwm" doesn't spike any more,
but the C1/C3 issues remains the same. I am running the machine
disconnected from any network when this occurs, and there are no other
apps active (other than Windows Explorer).

Does anyone else have this problem? Can anyone point me to a good
explanation of what C1 and C3 transitions are, how they interrelate,
and what OS settings can impact them?

Thanks,

Mark

Hi, Mark, unfortunately, I can't shed any light on this but I just wanted to
say that I have a new computer with similar specs to yours and have
experienced the same problem when playing music files. It became so annoying
that I finally downloaded Real Player which seems to work fine.

Hopefully someone will be able to offer some suggestions as to how to
resolve this issue.

Hi Mark,

I have the same Dell Inspiron E1705 and have noticed the same on my
system. In reviewing the dell support forum, I noticed many users with the
same or similar issue.

http://www.dellcommunity.com/support...=427571#M30729

I'm not at all happy with vista and the audio subsystem. It seems a little
immature. The audio mixer is lacking and the inability to monitor the
Mic/line in was a challenge.

Hope this helps.

Had something similar for a while. Go into "Control Panel", then "Sound",
select your sound device and then click "Properties". After this I select
the "Enhancements" tab and put a check in the "Disable all enhancements"
check box. Fixes for me on an Inspiron 1501.

No, I haven't noticed that but this being a "Dell Install" of Vista I guess
I wouldn't.

Now that you mention it when using Virtual PC of XP the sound seems louder
but that's probably my imagination. LOL

Hi, thank you so much for posting that. I just tried it and it seems to
work. I've only tested a few music files so far, but so far, so good.

Thanks again!

OK it's pretty simple to fix. Go to the Start "pearl", type in sound, (don't
hit enter), choose sound. Hi-lite speakers and headphones and click
properties. Then choose the enhancements tab and check the box that says
"disable all enhancements" Apply and ok and it's fixed. Good luck.
