The quality of service sensor checks on packet loss over each link in the network. The ping test sensor calculates packet loss rate and trip time at each device. Hdhomerun_config ffffffff set /tuner0/vchannel <channel number> hdhomerun_config ffffffff save /tuner0 null.

By lowering the value to 1100 all of my packet loss disappeared! Perform an initial packet loss test to check this issue. According to cisco recommendations, packet loss on voip traffic should be kept below 1% and between 0.05% and 5% depending on the type of video.
