I’ve got the electronic chirp as well, during playback of recorded shows via my wireless Roku (a 2 or LT, I don’t recall). It only started happening after the 2.2.2 update.
It happens when The Today Show hands off to the local weatherman and back again. It also happens between shows and commercial breaks. But I’ve also heard it in the middle of a commercial.
I’ve also heard it between two different commercials in the same commercial spot. Having worked at an advertising company part time, I learned a little bit. The sources of the commercials were most likely different, since one was an actual commercial, and the other one was a station self promo commercial “Magnum PI at ___ time” on COZI TV, which means it was a COZITV network spot instead of a KXAN media spot. It had to be a network spot because the time was Eastern and not Central like it would have been for KXAN since I’m in Austin, TX.
@TabloSupport going on two weeks and hoping you’ll confirm you got some takers to your request for some specific recording/timestamps as you never responded regarding the Live TV issue. Thanks.
@TabloSupport I still hear it? Can we please have a progress update? I do not hear it on my Roku 3 or Firetv stick. They are on a different tv than the t. In the bedroom.
Based on our investigation, we believe this may be an issue specifically with the firmware on the Roku 2 or lower. (Please let us know if you’ve seen it on the 3 as we weren’t able to reproduce it on that model.)
When transitioning to or from commercials feeds, broadcasters introduce a period of silence. What appears to be happening is that the Roku is employing a form of dynamic range compression, ie. they are boosting volume for very quiet segments and damping volume on very loud segments.
When encountering silence, the Roku may be over amplifying the audio causing clipping when full volume is suddenly resumed, which would account for a loud chirp sound. Following, we immediately hear a sudden drop and fade-in back to a normal volume level, again consistent with dynamic range compression.
For example, the graph below shows the wave form of the audio when transitioning out of a commercial. We hear the chirp when the volume is abruptly restored. The second graph is just an illustration to show that we do indeed have complete silence. Applying a huge amplification does not affect the silent period.
I hear it on Roku Lzt 2700x but not on Roku 3 but they are different tv. I can not move Roku 3. to where Roku LT is, but can move Roku LT to other tv. I assume the noise will move to the other Tv. When Roku 4 comes out, the Roku 3 mov red shirt to the bedroom and I’ll get a new TV.
I am watching a recording and din’t hear it. Only watching live.
We just bought a Tablo and have been using it now for about a week. We use Roku devices (wireless). We also are hearing a beeping/chirping noise at different times. It may be just during commercials. Is there any update on this issue having a fix?
@TabloTV It’s been 10 days since you posted the excellent description of what is happening. Any estimate when the problem will be fixed? I KNOW my problem will be going away because I am going to retire my Roku LT 2700x, move the TV and Roku from the living room to the bedroom (it is only 720) and getting a new TV that is 1080. Amazing what the price has fallen to. I am getting a Best Buy store brand TV (just dumb TV - I don’t need “smart tv” since I have a Roku.
Yeah…this is finally getting to me too. I have a Roku 1, 2 and two streaming sticks, and I’m getting it on all of them. It’s scares the animals. I’m really hoping somebody can fix this…
Since you guys are processing the audio anyways, can you add a miniscule amount of white noise to the silent areas?
(I’d say if not, to just add a miniscule amount of white noise to the whole audio stream, many dB below the hearing limit, but the purists would complain)
I’m considering picking the Google Nexus player instead of my Roku due to this (thanks theuser86). I missed the groupon deal, and am thinking about just buying it now or waiting for black friday/cyber monday.
But if you guys are close to fixing this, I may not need to upgrade.
