I just downloaded the trial version of MC11 and am using with a second sound card.  Regardless of wheter I drive the signal to one sound card or the other, playback has a scratching/popping which seems to cycle, sometimes cutting out the sound completely.

Tried upgrading to latest v11.  Do not have this problem with other media apps (iTunes) with either sound card.

I need to resolve this before commiting $$ for the full version.  Any ideas?

Try switching playback in MC's options.  WAV out or Direct Sound.

Welcome to the forum, Pelaf!

Surely it should not behave like that. At first we need more information. Please provide at least the following:

1. Your Media Center System Info from the program help menu (Help > System Info). It'll be automatically copied to the clipboard so you can easily paste it.

2. The soundcard models you have. Also the motherboard chipset info might be useful. Have you installed the correct and latest drivers for the souncards and motherboard chipset?

3. What file formats do you use? Does the problem exist with any file format?

4. Do you have any other sound related programs running at the same time?

5. Are the audio files on a local HD? Is it properly configured to use UDMA?

Tried upgrading to latest v11.

Did you install MC11.1.139? It is the latest. (The DL link: ftp://ftp.jriver.com/pub/downloads/music/MediaCenter111139.exe)

It may be good to reboot the PC after installing MC (just to be sure that everything installed properly). Did you do that?

As JimH said, sometimes changing the output mode has helped. I think the default is "Wave Out". Try "Direct Sound" and "ASIO" (if available). The options are here: Tools > Options > Playback > Audio > Output Mode.

Also, you can try to increase playback buffering here: Tools > Options > Playback > Audio > Output Mode Settings. However, I think this can help only to slow file access speed or network bandwidth related skipping.

Thanks.
1.  I am now running 11.1.139
2. both sound cards are soundblaster.  one is 128 live! and the other is audigy 2ZS.  I have not updated the drivers recently but will try this.
3.  I did some tests and it looks like only the AAC (m4a, m4p) files cause trouble!  mp3 seem fine.
4. no
5. all audio files are local.   Not sure about UDMA,  how do I check?

Yes I did reboot with same results.  I have tried various output modes with same results.

Thanks for your help on this...

I think you need the Directshow filters to playback aac in MC. Try doing a forum search for that.

Matt said in another post:

It may be possible to get AAC to play natively if you have DirectShow filters installed.  Otherwise, AAC will be played through the QuickTime engine.

I read another post that if you uninstall QT and install the Directshow filters that it played well...


Just a thought,
