SONY TV KD-49XH9505
If you experience random audio drops or interruptions whenever you watch or listen videos or movies on Youtube, Netflix, etc. even if the last driver installed from Sony (6.5076), read below the solution that worked for me.
I have tried many solutions to enable or disable few options from Sound settings but none except single one worked.
The ultimate solution that will eliminate such audio drops or interruptions on the above mentioned media channels is the following.
Enable Pass through mode - Auto.
You can do it from Settings as follows
Settings - Display & Sound - Audio output - Pass Through mode ( change from Off to Auto)
Hope this works for you all.
