# PiKVM V3+ Audio
|
|
|
|
This feature allows you to receive audio over an HDMI cable and transmit it to the browser in WebRTC mode.
|
|
|
|
!!! warning
|
|
* This is only supported by PiKVM V3+ devices right now. This may or may not work on other CSI devices as most have a hw defect.
|
|
* Please note the feature is experimental. Nothing will explode for you, but something may not work. Please report about problems [here](https://discord.gg/bpmXfz5) (preferred) or [here](https://github.com/pikvm/pikvm/issues/97).
|
|
* KVM switches may or may not work, we currently do not have a list of what works due to the feature being new/experimental.
|
|
* MIC support is not supported at this time, it may be supported in the future.
|
|
* USB Dongles do NOT support sound, there is no plans to make this work in the future.
|
|
|
|
!!! info
|
|
PiKVM V4 has enabled this feature by default.
|
|
|
|
|
|
## Preparing
|
|
|
|
1. Make sure that you have not removed the [jumpers related to audio (4)](v3.md#atx-connection) on the V3 board and have not deleted or commented out the `dtoverlay=tc358743-audio` line in `/boot/config.txt`. Return everything as it was, if you changed it. For V4 you can skip this step.
|
|
|
|
2. Update the OS:
|
|
```
|
|
# rw
|
|
# pacman -Syu
|
|
```
|
|
|
|
3. Edit `/etc/kvmd/janus/janus.plugin.ustreamer.jcfg` and add the following lines at the end:
|
|
```
|
|
audio: {
|
|
device = "hw:0,0"
|
|
tc358743 = "/dev/kvmd-video"
|
|
}
|
|
```
|
|
|
|
4. Enable the basic audio in the EDID:
|
|
```
|
|
# kvmd-edidconf --set-audio=yes
|
|
```
|
|
|
|
5. Reboot the device:
|
|
```
|
|
# reboot
|
|
```
|
|
|
|
6. Your host will detect the possibility of audio output via HDMI. Mac OS usually connects automatically, Windows requires manual indication, Linux will require a ritual shamanic dance. In any case, make sure that the audio is output via HDMI on your host. PiKVM supports stereo mode with any standard bits and frequencies like 32/44.1/48 kHz with 16/24 bit.
|
|
|
|
7. Open the PiKVM Web UI. Click the **System** menu and switch the video mode to **H.264 / WebRTC**. After that, the volume slider will appear under the switch. Increase it to the maximum and have fun.
|
|
|
|
!!! warning
|
|
* After the page is reloaded, the audio slider will be reset. This is a technical limitation in all browsers to avoid annoying audio ads.
|
|
* If something doesn't work, check the log: `journalctl -u kvmd-janus`.
|
|
* Try a different browser, try and clear browser cache before reporting issues.
|
|
* Unplug the hdmi cable and plug back in, either from the PiKVM end and or the target end.
|
|
* Please report about problems [here](https://discord.gg/bpmXfz5) (preferred) or [here](https://github.com/pikvm/pikvm/issues).
