Hello All;

I have been using amarok with ubuntu for a couple years now, ever since I started migrating my CD's to my PC. Lately I added mythTV on another LV and it also uses a version of SQL.

I'm wondering if there may be some conflict between my mythTV SQL and my amarok SQL???

Since installing mythTV my amarok has gotten more and more flaky. It used to play continuously for as long as I wanted to let it. Now it quits after almost every track and even crashes at the end ofa track on a regular basis.

I'm about ready to blow away the working copy of amarok and re-install a fresh copy from scratch. Problem is, if the mythTV-SQL install is causing some interference, how can I be sure that a re-install of amarok will restore its normal behavior?

Any ideas folks?
CT

If you are using an embedded MySQLe, there should be no interference.

This sounds more like a problem with the sound backend. Make sure to use the xine backend in Phonon, not the gstreamer one.

OK, a bit more info...

I'm pretty sure this is NOT an "audio" problem. Amarok plays fine. One track. Then it crashes.

When I restart it, it uses 100% of CPU on one core for several minutes. That's not a big deal since I assume it is re-scanning my collection (~33,000 files). My collection has not grown substantially in the period of concern (eg, <500 files). As stated earlier, the only substantial change on the system was setting up mythTV. Ergo....

I have not changed any settings, but here's the details:
I have pulseaudio for front end and xine for the back end.

Maybe this will help troubleshoot?

Thanks,
CT

What will help to troubleshoot is you running Amarok from the console,

Code: Select all

amarok --debug

You should be able to see what's happening when your CPU use shoots up.

Just a note -- PulseAudio helps some people, and causes endless problems for others. Amarok doesn't use it. You'll be using Xine-Phonon, actually. PA should be removed if it's causing your problems.

Valorie

Thanks Valorie.

I routinely have a shell or console open with 'top' running and I rarely see anything else of concern there. That's where I see cpu going to 100% for amarok sometimes. The only other thing that does gets >50% with any frequency is npviewer. In particular, pulseaudio does not get over a few % afaict.

Anyway, here's output as requested:
user:~$ sudo amarok --debug

NB; I used sudo b/c amarok was already running. I got a popup from KDE that said something like "pulseaudio has been removed".

I set amarok to use pulseaudio back when I was setting up the system b/c I was getting no audio with some multimedia files and pulseaudio fixed that.

I reiterate that all was working fine until recently and I do not think I made any changes that should affect amarok. This is mystifying me.

Best,
CT

You shouldn't be running Amarok as root. Please quit (control-Q) the other Amarok, and run with --debug. If you want to run more than one instance, run --nofork also.

If Amarok is crashing or freezing, you can do a backtrace. http://techbase.kde.org/Development/Tut ... sh_reports for more information.

Valorie

PS: if you have a lot of output, you might want to file a bug, and paste it in that info screen. If you decide to do this, please search the bug database first, and attach your information to a matching bug if you find one. Only file a new report if it's a new bug.

OK Valorie, I tried to do as you suggest. I hope the result is helpful; here is output:

I am confused by the apparent interruption and resumption of the command. Is this normal?

As of this writing, amarok is playing... yet to be seen how long it continues, but I will leave the shell open in case any further output occurs.

OK, Amarok played for about an hour or less. During that time it halted several times and had to be manually resumed by clicking on a playlist CD-icon. Eventually it crashed, but it played about 5 tracks continuously at the beginning.

Clearly this is one of those hideous 'intermittent' failures, but /here is the shell debug output/ from the last played track:

If you are getting a crash, you can get a backtrace. Please see http://techbase.kde.org/Development/Tut ... e_with_GDB for more information. You'll need this when you file a bug. Have you searched for bugs matching yours? You might do that first, so you can paste in your bt to that bug, rather than filing a duplicate. If you find no matches, please feel free to file a new bug. It's very important to give the developers all relevent info, since it's possible this isn't an *Amarok* bug per se.

Thanks Valorie,

I did rummage about looking for similar bugs. I got some with the search terms I used, but on inspection the circumstances were different, so this may be a new bug.

What gets me is that all was OK and amarok suddenly started misbehaving. Even now it will be fine for a while, then crash. I used to be able to leave amarok on, at least silent, for days to weeks with no problem.

I'll definitely do all I can to help the dev team, but this is very frustrating right now.

But please, don't paste this in the forum, a crash report definitely belongs to the bug tracker, as stated in this thread: viewtopic.php?f=115&t=67238

OK, folks- I figured this out; here's the scenario:

amarok regularly halted, scanning playlist or collection apparently, and using up to 100% of cpu (on one core). I can identify the behavior now because I figured out how to fix it.

First, I observed that the # of tracks listed for my collection was wrong. Also, some tracks would come up in playlist that I had deleted. So I deleted the playlist and copied the collection over to the playlist window [frame].

That didn't work. In fact, some of the tracks were then listed twice. Next I deleted the playlist and collection, set amarok to re-scan collection and rebuilt the playlist. Again, results were bad.

Finally, I created a dummy folder, pointed collection at that, let amarok scan it, then deleted the tracks in amarok (just to fully 'erase' stuff) then pointed amarok back at the real collection folder and rebuilt the playlist again.

That time it worked. The collection scan showed the correct number of tracks and the playlist was good- no duplicates at least. Since then amarok has been a bit slow between tracks (my collection is 80k+ tracks!) and new additions still cause amarok to chew up CPU, but it doesn't hang or crash anymore.

PS: I would have posted sooner, but I had router problems. But that's another story.
