Since installing Vista Ultimate, simple music playback using various programs is hampered by digital stuttering (similar to Max Headroom) from all music players. Vista can't get through a single song without these hiccups.

Occurs in: Media Center; Rhapsody; Winamp, WMP 11; iTunes about every 30 seconds.

My system is Windows Premium Ready; Acer Aspire 9800 (20" notebook) Dual-core T2600; 2GB RAM. Hardly lacks power; drivers not an issue on any of the aforementioned programs.

Anyone have this same problem, or hints at a source of the problem

Hi Steven,

I'm having the exact same problem!! What's more, there is an annoyingly painful delay between selecting a song and having it play back..

I am also yet to find a solution.

I'm running Ultimate 32 bit edition on an XPS M1210 with a T7200 core 2 duo processor and 2GB of RAM. I have a Geforce 7400 graphics card, so like you, it's not a result of a lack of power...

I'll let you know if I find a solution, but can you do the same for me

Thanks!!

I came across this article which kind of sheds some light (actually it confirms my suspicions)

http://www.stuff.co.nz/stuff/3931679a28.html

It's a DRM related issue. I'm not sure it will be fixable until Microsoft releases a fix...

Very good. Thanks.

I have no doubt that this is the cause of the problem.

Guess what

It appears that may not have been the problem at all, because I have a solution ;)

Take a look below;

.................................................................................
1. Go to control panel > sound > speaker > Propteries.
2. Then under enhancements.
3. Select "Disable all enchancements".
4. Enjoy your music without lag or delay!!
................................................................................

HAVE FUN!!

Very interesting. This switch did not fix my problem all the way, but definitely had an impact. It has lessened the lag time significantly. It does point a finger at Realtek Drivers, though.

I worked for an hour his morning with Vista support on this problem. They had me run a system file check and install the K-lite Codec Pack -- neither of which had any effect. They did accept the New Zealand technical article, but confirmed that the number of compaints on this problem is still relatively low and not enough to engage a major effort. At this time, they have classified the issue 1029496538 as "unresolved."

Thanks for your investigation and recommendation.

Thanks for the tips on the playback issue. I have virtually the same setup as you (XPS M1210, core 2 duo, Geforce 7400, etc.), yet the "Disable Enhancements" fix didn't do the trick for me. Is there anything else you did to fix the issue Are you also working with the "Sigma Tel HD Audio Codec"

This iTunes thing is driving me crazy!

Thanks for your help.

I am having similar issues when I try and play audio the CPU jumps to 100% and then after about 10 seconds goes down to 35% and then bounces up and down between 24% and 45%. After trying everything I could find online include the fixes mentioned above, I finally replaced my Audigy 2 Card with an X-FI. Unfortunatley that did nothing to fix the problem. I have an ASUS A8V Deluxe, AMD 64 3500+, Radeon 9700 pro. I was suprised to read Microsoft feels the problem is not big enough yet to require any major effort to resolve the issue. Maybe they better start Googling the problem. Having already replaced my router because of Vista, and spending countless hours dealing with power management issues, I am now going to go back to XP, the issues around Vista and Office 2007 are making me seriously consider switching our entire office to Linux and Open Office.

While the CPU cycle activity and New Zealand tech article had me convinced this was DRM, I believe it is a driver issue. I worked with Microsoft "escalated" tech support this weekend and they have closed the Issue 1029496538 as "resolved." They were adamant that this was a driver issue and not an OS issue or a DRM issue. My audio card is a RealTek High Definition AC97. Microsoft said they have a database already gathering numerous complaints about RealTek cards specifically and all are driver problems

This morning, Acer pointed me to a new page on their support site with Vista drivers for all their notebook systems. The RealTek driver from that support page fixed the problem. http://secure2.tx.acer.com/VistaDownloads/AcerSeries.aspx.

The problem is most likely related to DSP effects that you may have turned on, or that have been on by default. There is another thread that discusses similar problems, but seem to be directly related to an application called audiodg.exe. This app, from what I understand, handles DSP effects on behalf of your audio card along with some other things. It does appear, in some cases, to be the root of audio glitching under Vista.

I was actually having a similar problem and audiodg.exe was consuming about 14% of the processor. Audio "glitching" was most noticable when opening other applications or basically anything that required a moderate to high amount of processor time.

After turning off the DSP effects for my audio card, the glitching / stuttering had disappeared and audiodg.exe no longer consumed any processor time.

I beleive the true cause of the problems is not audiodg.exe, however. It simply falls into the hands of audio hardware manufacturers and their drivers.

I am currently using a Creative Labs X-Fi ExtremeMusic sound card, and while some DSP features cause no glitching (X-Fi Crystalizer), others do (X-Fi CMSS-3D). So, it would appear as though it is Vista driver progression and just a matter of time before all the glitches are sorted out.

Here is a link to the other thread: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1310814&SiteID=1&mode=1

Good luck and I hope this has helped.

Hi,

I try jazacoop tip and it's work.

But here more details about what happen.

Before use jazacoop tip I use "Explore" and clip on one video music clip.
And Windows Media Player (I use Vista Ultimate) open and begin play.

All work good and "audiodg.exe" use 5% of CPU.

But if I press "Library" "audiodg.exe" reach 20% of CPU.
And clip play bad.
And it's stay like that even if I press "Now Playing"

I try also this.
Windows Media Player is close.
I use "Explore" and select one clip.
Windows player open and play the clip.
So I choose with "Explore" other clips"
And all work good and "audiodg.exe" use 5% of CPU.

But if I save these music in a file and close Media Player and open it and open this playlist,
well "audiodg.exe" use 20% of CPU.

Vista is very buggy.

Now with tip of jazacoop "audiodg.exe" use all time 0 or 1% of CPU.
But I lose enhancements.

After some times, I find Vista ask a lot of power.
Better to have Dual Core (One core run Vista, the other run application)
And have minimum 4 MB of RAM.

MY machine (Pentium IV 3 GHz, 2 MB) miss power and I find that really a joke.

But not surprised to see Vista ask a Monster machine like a Cray computer.

Guys from Microsoft use all time last better powerful machine to create their stuff.

Well soon I uninstall Vista and put my "old" XP Pro.

It's pity to see Microsoft work for Bank or agencies like RIAA and not for their customer.

It's ironical cause Microsoft make their money because their customer and not cause Bank and RIAA.

Majority of stuff of Vista is for Bank or agencies like RIAA. And majority make our machine like snail now.

But sure Bank and RIAA have last machine with 4 Core CPU, 16 GO RAM, GeForce 8800, etc.

Why spy Customer Why not spy rich for change to see all bad things they do for normal people...

Anyway. All time same story. Money is God of this Planet !

Thanks Bill for this &@# # fake OS !

Happy to see my car not work like Windows.

Else for a long time I would have died!

Smile


Thanks jazacoop for you top anyway !
