Volume Slider sticks at either Mute or Max

[theloofa]

I am now dual booting XP and FC10. I absolutely love Fedora and rarely use XP anymore. However, I have a problem...


Adjusting the volume using the volume control on the UI works perfectly. However, whenever I try to adjust it using my volume slider, it locks at either max volume or mute. That is, whenever I try to turn the volume up, it automatically turns the volume to maximum, or if I try to turn it down it automatically mutes. This wouldn't be a real issue if it weren't for the fact that the volume level dialog box won't go away. It sits in the middle of the screen, leaving me unable to do anything. I can hit ctrl+alt+del and it will go away, but I would still like to be able to use the volume slider the way it's supposed to work.

I have no idea if this is a hardware issue or a software issue, and frankly have no idea where to begin. Here is my hardware profile:

Any ideas?


Thanks in advance,

By 'volume slider' are you talking about the special keys on the laptop for controlling volume?

[theloofa]

Yes, sorry for not explaining that. There's a physical wheel I can turn to adjust the volume.

A wheel is kind of unusual, the system may be having a hard time interpreting it.

If you run 'xev' at a console and turn the wheel, does it return some keycodes? A lot? A few?

EDIT: This is when I ran xev then turned the volume down

[AdamW]

Are you sure those messages came out at exactly the same time as you turned the wheel, and you weren't moving the mouse at the time? They look more like mouse movement messages. If you move the mouse it prints a ton of messages to xev, those ones can be ignored

[theloofa]

I ran xev again making sure not to move the mouse, and I obtained the same result.

I think the reason it shows so many messages is because the box that comes up indicating the volume appears and then disappears repeatedly.

[AdamW]

xev only prints messages for input events, that's what it does. I think it's possible that there's a bug with the input handling here, I'm not sure those events should really be generated. Tricky thing is, I'm not sure exactly where you should file this issue :\ It may be a kernel issue, I'm not really sure...anyone else know?

I am experiencing the same issue with my toshiba laptop's volume slider. When i hit ctrl+alt+del the problem is solved, somewhat, I also lose my keyboard and my system freezes leaving me with the only option of holding the power button and rebooting. I'm running Fedora 12 64bit
