* For HDMI-USB dongle, high latency and low video quality.
* General hardware video capture differs from software streaming and introduces additional latency.
* PiKVM can't transmit audio at this time. It will be available on PiKVM v3 HAT at some point in the future (implemented in the hardware, but doesn't have software support).

??? question "Does PiKVM support sound?"
At this time sound is not supported on any platform. Once sound is implemented, it will only be available for PiKVM v3 HAT. Due to a hardware bug in HDMI-CSI bridges, sound may or may not work.
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.

??? question "Can I have different hostnames for each of my PiKVMs?"
Yes! And it's easy to do! Using a SSH session or the web terminal:
1. Make sure you are root, run `rw` then run `hostnamectl set-hostname yournewhostname.domain`.
2. Optional: edit `/etc/kvmd/meta.yaml` to alter the displayed hostname in the web UI.
3. Run `ro` and `reboot`.
