We have a user using a HP gt7725 thin client running Linux. We are unable to get any sound from either the thin client or the remote session (RGS). The RGS session is running Windows 7 - all sound settings are correct on both the thin client and the Windows session. There is sound All we can hear is slight buzz when connecting a headset. In the sound settings there is also no indication that the client has recognized the headset connected. The only visible option is 'speakers'. We have tried connecting the headset to both the front and rear jack inputs. We have not tried with a USB headset.
