View Full Version : 6.5.1 => Nasty Electronic Sound on startup & Severe Track delays

This is really annoying issue.

[1] Sound
At the start of every track (mp3) theres a high pitched 0.25second nasty electronic sound....very similar to those you get with a ripping error sounding like a striking match. All tracks were playing ok with 6.5.0 (except these issues http://forums.slimdevices.com/newreply.php?do=postreply&t=28138) but after upgrading to 6.5.1 this error makes things unlistenable.

As I say, its already been posted by Neil (http://forums.slimdevices.com/showthread.php?t=28416) and that was with 6.5.0.

[2] Delay
There is now a long delay between tracks with high disc activity lasting about 30 seconds which was not previously there for me with 6.5.0 and 6.3.1. Cannot seems to track down why.

going to see if removing the plugins help.

My version is
SlimServer Version: 6.5.1 - 10265 - Windows XP - EN - cp1252
Server IP address: 192.168.0.6
Perl Version: 5.8.8 MSWin32-x86-multi-thread
MySQL Version: 5.0.22-community-nt
Nearly all MP3
WinXP

More on this.

I deleted itunesupdater1.9 and the delay has been solved. There seems to be an issue for 1.9 synching with itunes (at least when running 6.5.1). [James is it possible that updater doesnt work with 6.5.1??)

BUT

the nasty electronic sound (NES) is still there. On further testing => its there on 75% of tracks. Doesn't seem to be anything that distinguishes the 7500 with the problem (newly developed I hasten to add) from the 2500 that appear to be ok.


I await other people's further comments on this before rolling back to 6.5.0

I've seen similar problems with ogg files. As it turned out, for me,
it was a files ripped and encoded with an old version of the ogg
encoder. Reripping them (or as quick-fix to just re-encode the files)
fixed the problem for me.

If this turns out to be the problem, the OP could also disable the native
OGG handling and revert back to the transcoding technique used in pre-6.5.

I get this at the start of some of the MP3s I ripped with "Riptastic!" (I didn't use it for long as I soon decided it was a rubbish application). These files will play fine from a PC - they only make this noise when played via SS.

I haven't raised a problem on this before, as I'm in the process of re-ripping everything to FLAC anyway. When I find one of these, I just replace it with a FLAC version. It'd be interesting to know why it is happening though.....

This is probably unrelated but ...

I rip live mp3 streams from the internet. The ripped file starts mid frame. So the player must find the first good frame, by searching for the sync bytes and then validating. I suspect that slim does a less robust validation than other players, and thus sometimes gets confused at the start. It usually resyncs correctly.

The two symptoms are an occasional noise burst at the start, and bogus bitrate information displayed.

I have just started noticing this after I updated to 6.5.1 with the new gapless firmware.

It is nowhere near 75% for me more like 5%. Only on MP3's all either "bought" from allofmp3 or ripped using windows media player.

There is no electronic sound when played from Windows Media Player.

Make sure that you've done a full 'clear and rescan' after upgrading to the
gapless support. I suspect SD will bump the db version for 6.5.1 to force
this before the final version goes out (if they haven't already). If this
doesn't help please file a bug with the offending tracks.

ok I have done a full clear and re-scan under 6.5.1 => no luck,

Checked some tracks with 320 CBR / VBR => no luck

Most of my tracks are EAC => lame

For those of you wondering what it sounds like ....its like someone striking a match 1mm from your ear!

I also experienced this over the weekend. I installed the 6.5.1
2006-10-07 nightly into a clean directory, with only the latest
MusicInfoSCR plugin and a copy of my pref file. I haven't heard
anything like it before. Since only 1-2% of my music is mp3 and the
rest flac, I only heard it a couple of times. I was about to do some
troubleshooting tonight and came across this thread.

Progress => Just wiped off 6.5.1 + deleted plugins. Clean install of 6.5.0

Result => sound of a striking match at the start of each track is cured!

Conclusion => there is a serious problem with 6.5.1 and possibly a minor problem with 6.5.0 (in that some people get it occassionally with this verion too?)

Now I need to find out whether itunesupdater1.9 works with 6.5.0

I have this with MP3 files on Win XP (ripped ages ago, and fine for years)
since 6.5 - only on Squeezebox 2 though, not on Softsqueeze.

... on your system.

I have >9000 MP3's on my system and have not heard the issue you are on about. And I'm guessing that a lot of other people are running 6.5 and haven't experienced this issue.

Have you let iTunes muck about with your music? Have you switched on any of the replaygain settings when you don't have this info in your tracks.

Finally remove all plugins from your system and re-start the server.

If you are running anything other than the 6.5 install, then you need to discount that before you can blame the upgrade.

Just to add a "me too" to this.

The problems also happen on a large proportion of my MP3s and started after upgrading to the latest 6.5.1. I have tried turning off all 3rd party plugins & restarting, but this made no difference.

I don't think anyone has mentioned the bug for this yet. It is logged as:

http://bugs.slimdevices.com/show_bug.cgi?id=4312

Four people (including me) have so far added their experiences of this problem to the bug info. I'd suggest anyone else affected updates and/or votes for it.

By the way, this is not the same as the "RipTastic" problems I mentioned earlier in the thread. These are files that were playing with no problems under 6.5.

I have two different computers running Slim independently. For me, 6.5.0 works on both without the matchstick bug. I can confirm there is nothing wrong with the files themselves as (for me) downgrading from 6.5.1 to 6.5.0 solves the problem....so far. I have only played a hundred or so tracks with 6.5.0 and to date there is no sound at the begining of any track but I heard the sound twice in the middle....but I am not shouting about this because its hard to eliminate an track error. I need to do more testing.

I'd be interested to hear from people who have itunes + 6.5.1 running successfully (or not)

Seems to not like allofmp3 files, or could also be files which I've edited the coverart in iTunes.

The sound is just like dropping the needle on the old record players, sometimes "thump", other times "rip".

I'm experiencing the same problem, see here:

I found that this issue is really related to embedded coverart, at least the noise dissappears as soon as I remove the embedded coverart. I also found, that the noise is longer with big cover art. Another observation is, that files with coverart aren't played to their very end.

That's not the case for me unfortunately. I've just investigated one of my problem albums, and the tracks do not have any embedded cover art.

The ony tags in these tracks are: ALBUM, ARTIST, DISCNUMBER, ENCODEDBY, GENRE, TITLE, TRACK, YEAR

I don't use Itunesupdater, but the tracks were originaly ripped by Itunes (v4.9.0.17)

Same Problem for me. Nasty sound starting some of the tracks. I Don't use iTunes at all. The embedded cover art may very well be the problem and may explain why some tracks have it and others don't. I'll check on that soon.

Ah I see (sorry about the grumpy tone of my answer). Email sounds like a really painful way to read forums if you just get to see the latest posting rather than the whole thread! Doesn't that mean that you'll frequently be missing the context of posts unless the same information is contantly repeated in new posts?

I guess it is better than nothing though (if you can't get to the website due to workplace security restrictions etc.)

Email apps are much faster and better able to handle threaded conversations
which are pushed to you; I'd be a lot less active on here if the forum was
the only way to use it, which I know because of the complete lack of help I
provide on the sites I use which only provide fora. For one thing, every
last one of them has a different username/password requirement and many of
them have code to prevent your browser auto-saving that info, so I end up
having to ask for a reminder email every time I go try to use the forum...
and every one of them has a different place to do that. With all the stupid
avatars and page formatting and the thread ends up taking three times as
long to read, and I end up missing a lot of conversations that I would have
otherwise read.

The reason that the email user didn't remember the bug number is because
they were deleting the earlier mails. Changing your mind about the
importance of a conversation is not something technology can readily solve,
though the "view this thread" link to the forums in all the emails is a cool
feature that can help :)
