- According to a thread
at the AVForums, several Xbox 360 users are losing all sound after upgrading to the New Xbox Experience.
Evidently the problem only appears in HDMI-connected systems, but there has been one report of someone having the same problem using a SCART connector. Fortunately, there seems to be a fix.
ââ‚¬¢ Turn off the Xbox 360.
ââ‚¬¢ Remove the hard drive.
ââ‚¬¢ Turn on the Xbox 360.
ââ‚¬¢ When the Dashboard loads, put the hard drive back.
Apparently, the fix is only temporary. If you turn of the Xbox, you will have to receive the process.
