Please note that in a VDI world audio is usually generated on a server-side virtual desktop (i.e. inside a Windows system in most cases) and then forwarded over a protocol like ICA/HDX, RDP, PCoIP to the client. If you use Firefox, you need to enable the "Force execution as root" parameter in the Connection settings, otherwise Firefox will not be allowed to access the sound device.
'''IMPORTANT NOTE:
For RX-HDX and RX420(HDX) thin clients, the default audio setting optimizes the USB audio quality and performance. This may have a negative effect on analog audio. If analog audio (headset/speaker) or HDMI audio (built-in monitor speaker) is to be used, please follow the [https://support.ncomputing.com/portal/kb/articles/rx-hdx-audio-settings '''knowledge base article here'''] to configure the proper audio setting to provide best audio quality and performance.
== General audio troubleshooting guides ==
* If output works, but input (microphone) doesn't. Now this is very likely a problem in the settings of the protocol. While e.g. Citrix and RDP are capable of transporting microphone/audio input, please make sure that:
** you have audio input forwarding set to on (protocol-specific connection options).
** in case of RDP, you use FreeRDP. Only FreeRDP can do audio-in, the older rdesktop [[Rdesktop]] doesn't.
** in case of [[Firefox]], enable the "Force execution as root" parameter in the Connection settings
#* <code>soundinfo</code>
The audio parameter is formed like this: <code>"Card name",profile</code>
Looking at the soundinfo output, the "card name" is rather obvious - it is text within the quotes. The "profile" is one of these lines that follow the card name, the things like
It's actually very simple once you see it. For example, if you look at the sample soundinfo output below, these two possibilites that would make sense:
* <code>"HD-Audio Generic",output:hdmi-stereo</code>* <code>"HDA Intel PCH",output:analog-stereo</code>
as compared with the output below:
