My equipment consists of a Yamaha RX-A2000 receiver, Samsung LED TV, and a Epson 5010 projector all connected through HDMI cables. The HTPC is running Windows 7 Home Premium 64 bit. All worked fine when it first was setup, when playing a movie or audio from the HTPC it went into the RX-A2000 and sounded great. When I moved the mouse over the speaker icon in the task bar it showed the RX-A2000 as the sound device being used which was right. This all worked when either the TV or projector was on.
Now for the issue, weeks later it is no longer working and don't know what happened. When just the HTPC and receiver are on the audio shows the RX-A2000 as the sound device. As soon as I turn on the TV or projector the sound shows one of these as the sound device which is not right. Why is the receiver being bypassed? I want the audio from the HTPC to always send the audio using the RX-A2000 as the sound device. Also, when the TV or projector is on, in the sound device list the RX-A2000 disappears from the list. Any insight of this issue would greatly be appreciated. Thank you
