Running Audacity 2.4.2, Windows 10 Pro (10.0.18363), Lenovo E520 laptop, Logitech MX Master 3 Advanced Wireless Mouse using Logitech Options 8.36.86.
This mouse is equipped with a horizontal scroll wheel. When trying to scroll horizontally, the horizontal scroll bar at the bottom of the window moves freely left and right. However, the tracks remain fixed and do not move. Horizontal scrolling works in other applications.
That sounds weird.
If you click and drag the horizontal scroll bar, do the tracks move?
If “Pinned Play Head” is enabled (selected), try de-selecting it. (see: Timeline - Audacity Manual)
Yes, if I click on the horizontal scroll bar, the tracks scroll left and right as I drag the mouse. However, using the H-Scroll wheel on the mouse moves only the scroll bar, but not the tracks. H-Scroll shell functions as expected in other apps. Pinned playhead is not selected.
Does “Shift + Mouse wheel” over the waveform produce horizontal scrolling?
If it does, then can the horizontal scroll wheel be configured to do that with Audacity?
Update: A bug has been discovered in which horizontal scrolling does not work correctly when “Play at Speed” is paused. Could this be the problem that you are seeing?
This seems to be an issue whether Play-at-Speed is present or not.
This issue still exists. I’m using a Logitech MX Master 2S with a separate horizontal scroll wheel. Scroll bars move, but the tracks don’t. Using the mouse cursor to click the scroll bar will “snap” the track to the proper position… but at that point, it’s easier to just drag the scroll bars to begin with.
This old topic was about Audacity 2.4.2. Is that the version that you are using?
I can confirm that the reported issue is still present. Detailed info:
Operating System: Windows 10 Pro (latest updates at this moment / Version 21H2 / OS build 19044.1586)
Audacity version: 3.1.3
Issue description:
Horizontal scrolling by dragging the horizontal scroll bar works fine.
Horizontal scrolling using the horizontal scroll wheel of the mouse only moves the scroll bar handle, and doesn’t scroll the waveform/spectrogram view itself.
See also attached screengrab below (first part is dragging the scroll handle, second part is moving the horizontal scroll wheel).
Additional info that might be relevant:
I am experiencing this with a Logitech MX Master 3 mouse. The horizontal scroll wheel does work fine in various other software packages such as Cubase Pro, Chrome, etc…
As a quick follow-up to my message above:
The exact same hardware setup, running the same Audacity version 3.1.3 on macOS Big Sur 11.6.5 does not exhibit the issue (the machine is a MacBook Pro with both macOS and Windows in a dual boot setup, so I was able to test this).
Just another data point, which indicates it really appears to be Windows-specific.
Still seems to be an issue. The horizontal scroll wheel could be really useful to go through the timeline and it’s unfortunate that it does not work. Using the same mouse and the latest Audacity version.
I fixed this by assigning Page Up/Down to the Horizontal wheel in Logitech Options+
Hope this helps!
This is still a problem, as of v3.7.3.
Very specifically, it’s a problem with horizontal panning in Audacity when Logitech Options+ is running.
I tried uninstalling Options+, and the horizontal scroll works fine. But that’s not a great solution, because it means losing the keybinding functionality of Options+. I kept Audacity running while I reinstalled Options+, and as soon as Options+ started running, the horizontal scroll in Audacity stopped working properly (as described by other users: the scroll bar near the bottom of Audacity moves, but the actual window does not).
But the issue isn’t with the horizontal scroll wheel, it’s the whole concept of panning horizontally via the mouse. I tried binding Gesture Control->Panning to another button on the mouse, and while it will pan vertically as normal, the horizontal pan is broken.
Horizontal scrolling does work normally with shift+middlemouse though, as does plain old click+hold on the scroll bar.
(Windows 11, Logitech Master 3S.)
hey all, I’ve got some good news: The horizontal scroll wheel works just fine in Audacity 4! So while it still will take some time to get that version into an alpha or beta version, you can look forward to see that working when the time comes 
It’s not possible to fix this in Audacity 3.x, unfortunately.
