[SOLVED] Random Player Unresponsiveness

(1/3) > >>

Kernle 32DLL:
Hi ho,

Since a few days I experienced some situations, where rockbox enters a strange state of delicate unresponsiveness. This happens while a music track is running. The unresponsiveness has so far appeared when I was browsing files, looking at the "playing now" screen, and even when the player was locked and I did no input at all - so I can assume it's an overall problem.

The unresponsiveness shows itself in such, that the current playback stops (without any symbol indicating so). I can navigate through all menus with no probs, even select other tracks, but they won’t start (or at least "hang" at 00:00). As such, I have to restart my player. If I'm unlucky, that problem may appear again just some seconds after I restarted the player and chosen a new track to listen to. The lower bar, which normally shows which track is played next, shows a constant "loading..." by the way.

There were also numerous times, that under the same circumstances I got a slightly different outcome. Instead of the track just "pausing", I got a terrible loud electrical noise. Fun fact: I could start and stop that noise as if I was listening to music, but as the playback bar won’t move, I don't guess the actual track is getting played anymore.

I personally think, those are the same errors, only that in case one I don't hear the noise. Without much knowledge of rockbox, i would say this error is related to the function that "caches" which track to play next (aka "that lower bar"). I use the Ultimate skin by the way.

I hope you can help me track the error, since it is REALLY nasty if this happens, and you are standing in the subway, people all around you, and you just can't reach down to your mp3 player to either restart it, or just to turn off that terrible noise. Not nice indeed.

So long,
Kernle

PS: I use the Vibe 500 port

I'm not 100% sure I understand your question fully.

This appears to have started a few days ago, I get that.  Did it start after installing a current build, or had you not upgraded recently prior to the onset of symptoms?

Kernle 32DLL:
Well, the problem started a few days after I installed rockbox (current build). But as this "problem" occurs very random, I can assume that the problem was there from the beginning.

I managed to get some more information about the problems. Both seem buffer related, as I got some way strange PCM values in the buffering thread screen. The "silence" problem, where the music just stops, gives me a on the left side of the "/" a value that is far more greater than the value on the right side. Also, this value stays till I restart the player. The "noise" problem, essentially the same as the silence problem but with terrible noise instead of silence, gives me a very great, negative value on the left side.

Both problems have in common that if I jump to a different track after the problem started, rockbox seems to fail to get the IDv? data, as I only get a bunch of "?" instead of title information, bitrate, etc.

Sadly i don't have the means to create a screenshot or anything else more useful (unless rockbox has a build-in way to do this).

Hope you can help me :)

So long,
Kernle

Chronon:
Rockbox method is:
System > Debug (Keep out!) > Screendump

Then insert the USB cable to grab whatever is on the screen.

Gotcha, I'll provide you with some pictures then as soon as I can reproduce the error somehow when I'm at home.

Edit:
Happend during today's train ride. Luckily I had my Laptop with me, and as such was able to take some dumps. I dumped everything I fought useful. You can grab the archive here. Be aware that this archive is on my private webspace, and as such will only be uploaded for several weeks. So, if this problem points out to be a long-term problem, please make a copy to your own PC or webspace.

The second picture surely will be the most useful I think, as it clearly shows the incorrect PCM values. A note about the first picture: By "lower bar" I mean that bar that reads "Afternoons and Coffespoons"in the picture, just that you get what i meant earlier.
