That is the correct way to turn it on, it is a global setting and all future recordings will be made with the native AC3 audio track, so there is no conversion from AC3 to AAC (this goes for live TV too). Most of your devices should be able to playback AC3 audio.
No update yet. I’m traveling and I may not have time connecting to my Tablo.
Update: I just did a quick scan of all my recorded programs from an airport lounge and so far newer recordings (with the surround sound ON) are chirchirpless. So, this may have fixed the issue. We’ll see.
At LAST I think I found a solution. For years I have been battling the terrible chirping sound on CBS Evening News in both Salt Lake City and Seattle. I have finally eliminated it (I use Roku) by changing Tablo settings via computer to use surround sound and setting Roku to Dolby Digital. The loud sound of water dripping, or what some call chirping, went away!!!
Same problem. Did you ever find a fix for this problem? The video quality is excellent but the chirping sound makes watching the recording unbeatable. Tablo Dual using Roku for streaming back recordings.
Sounds like your Tablo has more problems than you think. Changing the recording setting to surround sound on should not stop it from making recordings. Open a support ticket directly with Tablo Support so they can look at your logs and see what’s going on.
With surround sound on, your Tablo is actually “doing” less work, it is not transcoding the native 5.1 AC3 audio to 2.0 AAC.
What is the make and model of your HDTV? Almost all HDTVs support AC3 passthrough over HDMI. You just need to have the correct Audio settings on your Roku (this is the system settings on the Roku, outside of the Tablo app).
TV Viso by LG 29LN4510. I did not see any adjustments on the Roku Streaming Stick + 3810RW. Could you direct me to the general area to find the adjustments? You can understand my reluctance to mess with adjustments because I already lost to TV show recordings.
You didn’t lose them, it sounds like the recordings are there are on the Tablo you just can’t play them back on the Roku. Do you have a computer with Windows 10, or an iPhone or iPad? You can try playing back the recording on one of those devices to see the recording didn’t fail.
