??? question "Does PiKVM support sound?"
Yes but the only officially supported version is the v3 Pre-Assembled or HAT's, v2 we will attempt best effort but ultimatly we do not support CSI modules or USB.

* Yes for RPi4 - Please see the main readme for splitter types listed under V2 Hardware
* Yes for RPi4 - Please see the main readme for splitter types listed under V2 hardware
* Yes for Zero W and Zero W 2, if using dedicated power you still need to split the power from the data towards the target. If using the target for power, this is not needed.
* This is not needed if you have a v3 HAT, as the HAT splits power and signal on the board.

## Video problems
??? question "I can see the video but I can't see the WebRTC switch"
WebRTC is an alternative mode for the default MJPEG and it's only supported on v2+ platforms with the CSI video capture device. See [this](webrtc.md) page to solve any problems with WebRTC.

??? question "My computer does not recognize USB of PiKVM V2+ at all"
* Make sure that you have used the correct USB cable with DATA lines to connect the OTG port for the Raspberry to the computer. You may have decided to use a USB hub instead of a Y-cable and **it won't work**. Use good cables and follow the instructions :)
* In rare cases, some very buggy BIOSes do not like HID and Mass Storage in one USB device. You can either [disable Mass Storage](msd.md#disable-msd), or use an [Arduino HID](arduino_hid.md) to physically separate them.

??? question "BIOS/UEFI does not recognize USB of V2+, but computer does"
If you are using a USB hub or USB PCI controller, this may not be handled by your BIOS. Try to use another USB port. Some ports may have a built-in hub on the motherboard and a buggy BIOS that can't handle it.

This feature is experimental and requires manual activation. Perform a full system update, edit `/etc/kvmd/override.yaml`, and reboot. After that, you can use remote wakeup by pressing any keyboard key or mouse button.

??? question "Buggy absolute mouse on Windows 98 as managed server"
How to fix:
* [v2+/OTG](mouse.md#fixing-the-absolute-mouse-on-windows-98).
* [V2+](mouse.md#fixing-the-absolute-mouse-on-windows-98).
* [Arduino HID](arduino_hid.md#fixing-the-usb-absolute-mouse-on-windows-98).
??? question "The mouse does not work with NVR/DVR CCTV"
Often these devices have a buggy USB driver that does not understand an absolute mouse and/or a mouse with horizontal scrolling. In this case, the following configuration for `/etc/kvmd/override.yaml` will help you:
```yaml
kvmd:
hid:
mouse:
absolute: false
horizontal_wheel: false
mouse_alt:
device: ""
```
It will make the relative mouse without horizontal scrolling the only mice.
??? question "There's big mouse latency on another Raspberry Pi as managed server"
Unusual case: RPi4 is used as a PiKVM to control RPi3. In this case, the mouse delay may be several seconds. To fix it, append `usbhid.mousepoll=0` to the boot line in `/boot/cmdline.txt` on the managed server (i.e. RPI3 in our case) and reboot it.
