Thanks for the reply. I would like to have the sounds working properly and be able to use them and would be prepared to try to fix it, just don't really know what needs fixing and how to fix it.timrowledge wrote: ↑Mon Apr 22, 2019 11:10 pmThere has long been a problem with balancing sounds in Scratch on the Pi; it seems to work ok on other platforms.
The issue normally appears to revolve around the 'reverb' mixing setting within the Scratch system. Having reverb turned on can make for some annoying sounds - but only in some cases, just to be more frustrating - whereas turning it off can result in short sounds (like 'pop') simply not getting produced. It's possible that kernel/sound-system changes since the last release at the end if 2016 might have improved this.
You can work around it with some rather fiddly poking. Is this enough of an issue that you are prepared to spend 20 minutes or so doing strange things in a language you've probably never seen before?
Thanks very much. Hope it is possible to fix.
Thanks for the new version - downloaded, unzipped to the home/pi folder and then tried to copy to usr/share/scratch. It tried to copy and then said I did not have permission to put it there.timrowledge wrote: ↑Mon May 20, 2019 11:12 pmHere's an experimental new version for you to try out; unzip it and move it to /usr/share/scratch.
http://www.rowledge.org/tim/squeak/file ... .image.zip
The /usr/bin/scratch shell script (which handles the menu item for Scratch on the desktop) should pick it up as the newest image file available and run it ok.
To test out the reverb preference, make a simple text file in your user home directory (ie /home/pi) named 'scratch.ini' and insert a line
to stop the reverb effect and
soundreverb=1 to enable it.
If this doesn't solve the problem then it would seem likely to be a lower-level issue needing to be brought up with Pi Central, so let's hope...
Used this and the image is now copied to the correct folder. Opened Scratch from the menu and the latest version opened correctly. There is now sound but still with the same problem as before. Tried making a "scratch.ini" file and setting the soundreverb=0. It made no noticeable difference. Was really hoping this would solve the problem.
I am having the problem with all the sounds included with Scratch, and all the pianos/instruments/drums as well. Haven't tried importing or recording sounds to Scratch. I played music from a USB stick and it sounded normal, no echo. I will try importing said music to Scratch and see how it sounds. I am using these speakers: https://www.argos.co.uk/product/8651774 , connected to the powered USB of the monitor and the audio lineout of the Pi.timrowledge wrote: ↑Thu May 30, 2019 4:53 pmSorry for the delayed reply -
well, that's annoying. I hoped the issue would be nice and simple to fix
Please tell us about exactly which sonds you are having problems with and exactly how you are listening to them. Via hdmi to speakers on a monitor? Headphones plugged into the lineout jack? Sound HAT of some sort?
If you can, record the sound and upload a file so I can hear the effect myself. Any information you can think of relating to the sound and how it is being used might help. Have you tried playing any (or ideally, the same) sounds on your Pi directly - via one of the linux sound player doohickeys? It's not impossible it is unrelated to Scratch itself.
Odd. I wonder if it is specific to my Pi or batch of Pis? I hear a small echo at the end of almost all sounds in Scratch, and there is almost no difference with the reverb on or off in scratch.ini (currently I have it off, just because it is supposed to make it better). I have had no issues using the same speakers with a Windows PC and a Chromebox and have played the Meow from the online version of Scratch. It did not echo, so I know it is not the speakers themselves. Only had my Pi about 6 months and made a new SD card with the latest Raspbian when I got it. I regularly run the sudo apt-get update, sudo apt-get dist-upgrade, so I am always running a new-ish version.timrowledge wrote: ↑Sat Jun 01, 2019 5:58 pmI've been trying out some sounds on one of my Pis to see if I can replicate your problem; and the answer is no, I can't.
Even with reverb on, the only sound that is really noticeably affected is the cat meow. Pretty much any other noise is ok. Turning reverb off makes little difference except to the meow. This is puzzling.
I'm using a pair of random junk-pile powered speakers connected via the headphone socket. They even look pretty similar to the ones you are using!
The only thing I can think of now is that at one point the sound output from the headphone socket was, to put it mildy, terrible, especially for quiet sounds. That was at least a year, possibly two ago though, so I hope you've updated your Raspbian since then!
Just to be clear - did you mean that you have used a USB sound out dongle and Scratch sounds were ok through it?
Here is the sound file:timrowledge wrote: ↑Sun Jun 02, 2019 11:59 pmI simply can't hear any problems with sounds on any of my Pi's. I don't know what to suggest next.Maybe record the sounds on your phone and post the sound file (you'd have to at least zip it to be able to upload it here) somewher. Maybe if I hear it I will recognise some symptom?
