DMA 2100 - Audio Quality problems when playing mp3 or wma files

I recently purchased a DMA 2100 - two weeks ago.
Plays my streamed DVDs (VOB files) along with streamed video off the internet wonderfully. I'm impressed that it actually seems to upscale my DVDs and the Audio quality is perfect.
But when I try to play a simple mp3 or wma file I experience pops, clicks and short dropouts during playback.
Obviously my network is more then sufficient to push DVDs across reliably it should be able to push mp3s/wma files. Network performance monitor shows me in the low end of HDTV capable and stable. MP3s and WMAs are stored on the same disk as my DVD VOB files hence I don't expect there is a problem with my media center PC serving them. (PIII 3.0GHz, 2.5GBs, 2TB RAID 5 SATA Array)/ I was experiencing some problems with playback on my PC but that was resolved by upgrading the drivers for my audio card SB Audigly 2
Any ideas?

Looking further into this I also notice that my Media Center PCs processor is running all out 70%-100% processor utilization when streaming the MP3s or WMA files.
Meanwhile when streaming DVDs the processor is at a rather lazy 10% or so.
Anyone, any ideas why when Streaming DVDs my audio would be perfect and processor idle.... but when streaming WMAs my processor is pegged and the audio pops and crackels as it plays?

Audio Sync Problem When Playing on iPod

I just got my video iPod and have been encoding some .avi's using Xilisoft. When I play the output as a .mp4 it's fine on my laptop, but when I play them on my iPod there's a distinct audio sync lapse that gets worse as the players goes. Many videos also freeze at 1:51 (even though the time indicator shows the whole file time).
Anyone else having this problem and found any solutions?
Thanks.

Itunes delays ONLY when playing mp3's. Also it delays when I move any file type into a playlist. Help! I'm about to go back to Windows Media Player!

Hi friends! Like I said Itunes delays ONLY when playing mp3's. Also it delays when I move any file type into a playlist.
Here's what I've done so far;
I 've checked my external hardrive (by playing it off my internal instead), I've tried reinstalling (although it wasn't an uninstall), I've tried clicking on all the neccesary boxes (let itunes organize files, copy files, consolidate, and reorganize), I've tried different sound cards, I've tried moving files quickly (as some have said this works). I'm not sure what's wrong. I have 7000 songs.
Any help would be great!

Have you tried installing Media Manager on another computer and streaming the songs from there?
How about smaller playlists? See the same problem?

M57 audio quality problem

Hi everyone,
I have 3 M57's with onboard Soundmax sound devices that have been downgraded to Win XP Pro w/SP3 and all of them are exhibiting audio quality problems. It seems like that audio is distorted most of the time. As an example, if a wave file is played 5 times it may sound distorted 3 out of the 5 playbacks. The only way to describe the distortion is it sounds like the audio is being downsampled to 1kHz.
I've also tried using speakers, headphones, etc.
Any help would be appreciated.

Well, at least it's not just me. We've got over 100 of these workstations to roll out and I can't get the audio to work either. It's the exact same problem that mlieberum is having. I've tried about every single thing I can possibly think of. Everytime I think I've got it working, all of a sudden the sounds starts distorting. Something weird that I've noticed is that if Windows Media Player is open and playing music, the audio works all the time. As soon as you close media player, the sounds starts distorting again.
I've contacted Lenovo twice and they were absolutely no help at all. I've got to have 40 of these workstations done by the second week in January so I need to figure something out. If anyone has any ideas, I'd certainly appreciate it.
Thanks,
Steve

MicroStar NX6800GT-TD256 256MB AGP - problems when playing movies

Hello,
I have just upgraded from MSI Gf FX 5950 ultra to MSI 6800Gt AGP, and I have problems when playing all movies.
Movies are VERY overbrightened, and there are some color issues too.
I have tried installing various codecs, nothing helped. {I did a fresh installation of windows XP, and I installed win media 9 codec, indeo codec, and Allin1 codec ver. 60.27 }
i have also tried to play movies in different movie playes {BSplayer, win media player, MSI intervideo}, still same problem.
I never had such a problem with my old FX card.
In PC games, there is no problem at all, all runs perfectly.
Can anyone help me pls?
thank you for any tip.

[SOLVED] unable to play mp3 or flac files in mpd, .dts files play fine

I had a perfect running mpd setup before I tried to fiddle around with some dependancies to get xbmc-svn to compile without errors. I installed some AUR packages (ffmpeg-svn, x264-git, libva-sds, libvpx, libid3tag).
After that I started to experience trouble with mpd, it start fine and says it plays audio files just fine but whenever i play a mp3 or flac file the progress bar just looks like it's playing the file but I hear no sound. Whenever I play a .dts file i hear the sound correct.
I'm very curious to why this happends.
I rolled back the packages mentioned above but the issue remains unsolved.
My setup: pc is connected to receiver by hdmi cable using the latest alsa version with digital passthrough over hdmi, currently using mpd-git from AUR

Playing thu car stereo that only supports MP3 or WMA files

How do I get my ipod to play thru my car stereo.. it appears my car will only recognize MP3 or WMA files. Cant seem to find a way to have ipod files be created in a format that will work with my car stereo.. Help???

You can convert songs by using the iTunes Advanced menu -> Create XXX Version. What type of version is controlled by the encoder selected in the iTunes Preferences -> General pane. Click on the "Import Settings" button to change.
When you use this, you will get an MP3 copy of each song you convert. You can find them in your library by sorting by the "kind" column and searching for "MPEG audio File".

Help!- MP3 and WMA files no longer playing on my Micro Pl

I have a 52mb micro plus that I got in September 2005. All of a sudden, I can longer play my mp3 and wma files... just the radio. I have updated my creative zen file organizer, I have a full powered battery inside, I have done no significant damage to the player (I dropped the player once on the sidewalk but not from a big distance or very hard), and I really can't think of anything else that is causing the problem. Can someone please help me fix my player so I can start playing my music files again? Thank you.Message Edited by jjc92787 on 05--200707:0 AM

No unfortunately not. I don't know how to escalate this to Apple tech but I think that is the next step as I believe it is IOS based problem, not user related.

Why does Acrobat Pdf converter file slow down my 2003, Windows Word Program. I only experience this problem when i convert a pdf file to a doc file.

Hi Bill -- thanks for your reply!
When I check the Document Properties on Acrobat I can see that the fonts used in the document (Cambria, Times and Windings) are listed as "Embedded Subset" in the Fonts panel. The machine it was created on did use an earlier version of OS X and an old version of Word, but it seems to have the proper fonts...

Mixture of mp3 and wma files on my muvo

I got a muvo tx last week as a gift. I copied about 250K of mp3 and wma files to it from my laptop running windows xp pro. The player plays all of the mpe files with no problem but won't play any of the wma files. The wma files were ripped from a cd using Windows Media Player.
Any advice on playing the wma files will be appreciated. The little manual that came with the player says it will play mp3, wma, and wav files.

JimR,
For WMA audio files with DRM protection, you will need to use either Windows Media Player or Creative MediaSource application to do the transferring of the files to the player. Only by using these application can the license be transfer to the player to allow playback.
Try ripping the Audio CD again but this time go to the Windows Media Player 9 setting option and ensure that the 'Copy protect music' option is disabled.

How do I convert an mp3 or WMA file to a m4a file?

I read on another forum that iTunes can convert mp3 and wma files to m4a format.
How do I do this?

That is correct.
By default if you load a .wma file into iTunes, it will AUTOMATICALLY convert it to another format first, since it needs to in order to play it. However, you can also convert any other file format that iTunes supports, assuming it can get loaded into iTunes.
To set what format you want to convert to, go EDIT->PREFERENCES. Click the IMPORT SETTINGS button and select which encoder you want (AAC, MP3, Apple Lossless, AIFF, and WAV are supported) and then select the bit rate if you are choosing a lossy format (AAC/MP3).
From there, any .wma files you load into iTunes (you can do this by going into iTunes and selecting FILE-> ADD FILE TO LIBRARY, or simply right clicking a .wma file and OPEN WITH iTunes) will convert to that format. ALSO, if you have any other files already in iTunes you wish to convert, select the file(s), and go to ADVANCED -> CREATE ___ VERSION (the blank being whatever you selected before) and it will convert for you.
Remember, converting a lower quality song to a higher quality format/bit rate won't "up-covert" any quality, the lowest quality you start with is the highest you can possibly get, but if you still prefer to have a certain file format or bit rate to compress to, this is the feature you'd use!
Let me know if you have any other questions!

Maybe you should try to convert from wma or rm to a supported format before attempting to play it.
