The 355 update has obviously changed something in how audio is processed. My normal audio setup uses the TV speakers through a HDMI connection. Every few minutes there is a one second aduio dropout. The video is normal. Replaying the section with the dropout will play will audio intact. The frequency of this new bug is quite disturbing. I've done some experiments to help track down the problem and encourage anyone else who is having this problem to do the same and post here so Dish can fix this ASAP! Since the dropout is happening on TV1 I first tried to change the audio sync from HD to SD. This made no difference. The dropout happens on SD or HD channels. I don't have OTA. I did a cold reboot of the receiver and the dropouts were still present. My next test was to use my alternate audio hookup which is an optical link to my surround system. With my 942 the sync was so bad I'd stopped using this. I'm glad to report however that I didn't see any audio dropouts with this connection! Could someone who is experiencing this problem test the audio connection with component to see if the problem is there as well? Thanks!
