Winamp crashes when connecting MTP device
 

Ok, I have the latest version of Winamp (5.531), and whenever I connect my Philips SA6025 portable player, winamp simply crashes. I tried everything, rebooted my PC a few times, formatted my player, nothing! And what bothers me is the fact that it used to work with an older version of Winamp 5!
Oh, and also, providing assistance only through a forum seems a bit stupid to me. I searched your site for a simple e-mail address like support@winamp.com but didn't find one...

Re: Winamp crashes when connecting MTP device
 

I'm experiencing the same thing with a Sandisk Sansa Fuze. I don't know about older versions of winamp, it's a brand new player. I've tried this on a few different systems so far (all XP), even a freshly formated SP2 system with nothing else on it besides WMP11 and Winamp 5.531. All crash as soon as I plug the device in, or if I plug it in prior to launching winamp, it crashes as soon as winamp opens.

It throws a couple of errors. The first is a generic memory could not be written error. The second is a Runtime Error R6025 - pure virtual function call.

This is the exact behavior I'm getting, although I get no errors. Will there be a fix for this? I just HATE managing my music with WMP!!

If you want to use Winamp to manage/sync your P4S/MTP device, then for WinXP, you'll need to rollback to WMP10 (WMP11 takes over the system and causes conflicts with other software that try to interfere with it).

We're looking into the matter to try find a solution,
but have had no luck so far...

Basically, WMP11 is always running in the background. So when you connect the device and try to manage it with Winamp, Winamp can't complete the task because WMP11 has already detected it. Therefore two separate processes are trying to open the same drivers/libraries at the same time...

Oh, I see, thanks a lot for the info! This makes me hate MS and WMP a little bit more :D. Good luck with fixing it!

You could always try closing WMP11 completely if that causes the interference.

Open Task Manager (press CTRL+SHIFT+ESC)>Processes tab>find wmplayer.exe in the list>right-click, choose end process. This completely closes WMP11.

DJ Egg thanks so much for clarifying that this is being investigated. I wrote a couple of reports in the official bug report thread and never heard anything after that. It's reassuring to know someone's actually looking at it.

The problem for some people is if they own a Zune and another MTP device. The Zune software automatically installs the WMP11 SDK and won't allow a rollback, effectively making it impossible to use an MTP device with Winamp.

Thanks again for the confirmation. Good to know it's not being ignored!

Mhm. Like before with WMP10, I didn't want to install the complete WMP11 package, but the MTP drivers only. After a little bit of trial&error I managed to extract them from the package as standalone-installable.
So no other WMP11-related processes are running on my System, but Winamp crashes everytime I connect my Sansa Express.
Conclusion: The crash isn't caused by some WMP11-related process, but the driver itself.

But: Winamp is running and working after the crash, if I ignore the "Winamp has crashed"-Window, I'm able to manage the MP3 player with Winamp as if it didn't crash.
If this effect is not limited to my System, could it be an usable workaround to intercept and ignore the conflict that causes the crash?

Wow, good on you for trying that out.

I've come to the conclusion that it's not necessarily WMP11 and related processes, but perhaps the problem lies with how Winamp implements MTP.

Even using Winamp with WMP10 and MTP, things aren't quite right. In Winamp ratings don't get transferred correctly, and album art can get lost. It also takes approximately *forever* to "load" the portable device.

However, if you try the same exact transfer using MediaMonkey (blasphemy I know), not only is loading the device a snap, but the transfer is much quicker, ratings are transferred fine, and so is album art.

*shrug* I can't say I know what it is, but it does seem to me like there's something off about how Winamp handles MTP in general. It's sad because I'd much rather use Winamp than any other media player.

I'm having a similar problem with Winamp v5.541 crashing when my Sony MP3 Walkman NWZ-S738FNBC is connected. I am running WinXP SP3 and WMP10.

If the Sony MP3 player is connected first and then I start Winamp, Winamp crashes within 1-2 seconds after starting. If I start Winamp first then connect the Sony MP3 player, Winamp will crash about 60-90 seconds after connecting the MP3 player.

Oooops, my fault. Extracting the WMP10 drivers was a little bit tricky, WMP11 is quite easy.

Start WMP11-setup, wait for files to be extracted, locate temp dir (in windows temp dir - or use Sysinternals Process Explorer), copy umdf.exe (User Mode Driver Framework) and wmfdist11.exe (Codecs, MTP, ...) to another directory, install both of them, done. :D

Well, that's not "MTP only", as I thought (it's been a while, didn't remember correctly...), since at least the WM11-codecs are installed, too. But it's codecs and MTP without WMP. :p

same symptoms with Samsung Omnia
 

I have the same symptoms with a samsung Omnia. I've tried rolling back to windows media player 10 but that doesn't fix the problem.

Anyone have a fix for this?

I am having the exact same issue with my sansa fuse

What if...
 

As we all know, Winamp curb stomps WMP any day. So if the problem lies with WMP, then just uninstall WMP from your computer. (and make sure windows dosen't try to put it back on through an automatic update!)

By the way, I am having the same problem with my Sansa Fuze (4G). I just thought of this idea while reading the posts on this subject.

is it not possible to disable the WMP services?

Here the same issue with my Nokia N85 in MTP mode (PC Suite mode). A workaround here... http://forums.winamp.com/showthread....mp+crash+nokia
