Can you provide an example that we can test? Try downloading Firefox from Mozilla, run it from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

Operating System: openSUSE Tumbleweed 20220525 KDE Plasma Version: 5.24.5 KDE Frameworks Version: 5.94.0 Qt Version: 5.15.2 Kernel Version: 5.17.9-1-default (64-bit) Graphics Platform: X11 Processors: 4 × Intel® Core™ i7-4810MQ CPU @ 2.80GHz Memory: 31.0 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 4600

Thanks for the quick reply!

I downloaded firefox ( latest version - 100.0.2 ) using your link and ran it in from the unzip folder. Same result.

I can send you the mp3 is you want to try it yourself - nothing private in it.

I fixed the situation temporarily by converting the mp3 to am Ogg Vorbis format. This one fast forwards/back normally. But the mp3 format is more common and more desirable.

PLMK if you want the file...

Thanks,

Send a link. I can use the arrow keys in Windows with no issues.

Here's a link to the mp3 that is having the issue.

file is called DickD-interview.mp3

Thanks for your help...

On openSUSE, I'm having the same issue with your file with a bitrate of 117 (lower quality). When I tried one of my files with a 192 biterate, I was able to use the arrow keys with no issue.

I would try a higher quality file and see if it makes a difference for you. The lowest I have is 128 bitrate and it works for me.

Also, download Firefox from Mozilla to see if it has the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

If I go beyond about 9 minutes then the file plays properly when I go forward and backward. Before 9 minutes it takes a while before I hear sound if I move the position, but I see play indicator moving so only the sound is missing. Looks that Firefox isn't able to decode the MP3 file to seek to the new position.

OK. I found what seems to be the solution, though not completely sure why.

The export settings on the file were "preset" ( Lame preset ), with a bitrate of 170-? kbps - this sounds like a variable br..

When I changed this to "Constant" and a bit rate of 128, the arrow keys work as expected. Probably all of our mp3 files are encoded that way, but somehow this one had the "preset" clicked.

I also tried VBR, quality level 5 - that did not work either.

Anyway, FWIW, there it is! Thanks for pointing me in the right direction.

Mark it resolved and enjoy. ;-)
