Volume resetting

[Karanight]

I've noticed that the volume bar moves or resets on it's own. When I play tracks at full volume the volume resets to about 20% below full volume after several songs. It happened twice last night and the second time it happened I left it where it had reset.
Another problem I've noticed is if I play tracks with the volume set off, After several songs the volume resets and I hear the track and I need to reset it to off again. I realise that its unusual to play tracks with no sound but I do have times when I need to do this. Sometimes I'll play a dozen or more tracks with no volume change and then the volume resets.

you must have picked "controls->remember song volume" on some songs.

context click in the sort column headers and pick "volume", then sort by that column. all the songs with volume set will filter to the top.

I suppose it's a bug that kJams doesn't put the volume *back* to what it was before, after that song plays.

I haven't used the controls->remember song volume ever but I now think that it's something to do with Time Machine.

I have a Kj working for me who is not computer literate, and I've not shown her how to remember song volume, I was with her last night and a message came on the screen saying Time Machine backup had failed. Then the next song had no volume at all. I looked at the volume on kJams and it'd gone down about 20%. I then looked at the volume setting for the mini mac and it was all the way down.I turned time machine off and had no further problems. I have time machine running on my macbook pro so I'll turn it off and see if it happens today. I'm doing a 9 hour stint with kjams today so if the problem is with time machine I should have no problems
I'll report back tomorrow.

[dave]

i am utterly confused about how time machine could have anything at all to do with it. the ONLY possible way for this to happen is if the user manually and specifically sets the "remember song volume" option.

I've just done a 9 hour kjams session with TM turned of without a single volume problem. I will set up at home with TM turned on and see if I have the problem again
Edit
I played 5 tracks with the sound off after which the sound reset to about 20% of the full volume, TM was turned on.

Reset to zero and after 10 more tracks the volume went to about 10% of the full volume.

Reset to zero and played for 90 mins without a hitch.

not easy to pin down but the sound does change. I'll shut down and start again and see if I can recreate it with a few tracks.

[dave]

did you or did you not reveal the "Volume" sort column in the browser window?
the volume does NOT change by itself, it changes when there is a number in the volume column.

[Karanight]

I've just put the volume column in the browser window and all the tracks have a dash, there's no number for any of the tracks.
This volume change happened on two different computers, a mini mac running leopard and a macbook pro running Leopard Snow

[dave]

so you're saying that the kJams volume control knob actually changes out from under you? you're NOT saying that this is the MacOS volume control, correct?

[Karanight]

When I first notice this the volume on the macOS went from full on to zero and kjams had gone down about 20% You're correct that the volume change has nothing to do with time machine. I've just had the volume on kjams turn down with TM turned off.

I was testing it out and I had the volume column in the window. There was no numbers in the column, when the third track played the volume went down and the volume column showed 0.06 When I started the test the volume was turned all the way up. I don't understand why there was no number in the volume column when I started, but it did appear

[Karanight]

I've put a dash where the 0.06 was and retested it and the track played at full volume with no change.

[Karanight]

Here's what happens

[dave]

the volume on the macOS went from full on to zero and kjams had gone down about 20%

if this is really true, then there is some script or something doing this on your computer, entirely unrelated to kJams.

The MacOS volume and the kJams volume are about as related as the Moon and an Orange seed. If they were both affected in the same way at the same time, the only possible explanation is because some PERSON made them become affected. It is simply NOT POSSIBLE for one to affect the other in any way under any circumstances.

Having said that, i'm utterly baffled by your testimony of events. I see your screenshots show nothing in the volume column, then suddenly there IS something in the volume column. I just looked yet again at the code behind this and have confirmed that the ONLY way for something to get into the Volume column is for a person to put it there. So i must wonder, do you have a keyboard shortcut set to "remember volume" or a script running or *something*??

Note that the song must have something in the volume column BEFORE it is started playing. so that screen shot must have shown the volume set to 0.2 sometime before the song played.

If you can reproduce this bug AT WILL, that is, re-create the problem happening 100% of the time (every time starting with nothing in the volume column) i would be most grateful. Let's get to the bottom of this!

[Karanight]

I haven't got a shortcut to remember the volume.

I've just reopened kjams to check if there's a shortcut to remember the volume and there wasn't. but I did notice the track you see in the 2nd window thats got the number in it, now has a dash. I didn't change it to a dash.

I've searched my lappy for applescripts with volume and found none. I'll re-run the test again later and report back. It's doing my head in.
I'm wondering if there's an applescript on the HD, that might be the reason I'm having the problem on both computers, I mirrored the HD's. I'll check later.
EDIT Just looked at the HD, No applescript found.

Also I closed kjams and re-opened it and the track now has the number 0.02 back in the volume column.
I've found about 25 tracks with the volume set between 0.02 and 1 so I've put a dash in everyone of them. Hopefully it's the end of the problem
I have played about with applescripts and volume in the past and this might be a legacy of that. If it is I should have no more problems. If I do I'll get back to you.

[dave]

ok. you know you can set identical meta on a selection of songs at once? eg: to set all 25 of those tracks to have "-" volume, just select them all at once, then set the volume on one of them to "-" and they'll all get that value (of none).

please keep me posted, i am most curious.
