Sound warbles up and down in volume for about 10 seconds when initially turning on TV and device then levels out to normal.

Litzdog911 and DIRECTVhelp,

Thanks to both of you for your suggestions on resolving my audio warble when initially turning on my Directv device for the day. I disconnected my Polk Audio sound bar and use the audio from my Samsung TV and it worked! No sound issues when I turned on the system this morning. Obviously a problem in the sound bar or fiber cable connecting the TV to the sound bar.

Again, many thanks for your time and persistence to help resolve the sound issue.

DirecTV Stream? This is the satellite equipment forum. I'll move to the correct forum. 

What streaming device(s) are you using? Which one has the "warbling" audio issue?  How is that device connected to your TV? Soundbar? AV Receiver?

I am using Directvstream receiver device bought from Directv. The audio on my TV is muted and the device is set to operate the audio from my Polk Audio sound bar. The DTv remote setting reflect that sound choice in Settings menu. The sound bar is connected to my Samsung TV with the fiber optics jumper. Connections have been checked and they are tight. The sound goes from normal volume to very low level as though you were taking a volume knob and turning it up and down repeatedly for about 10 seconds then the sound becomes stable at the normal listing level. This only occurs when the device is initially turned on for the day. It can be turned off and on several times during the day and the level comes on properly each of those times as it always has. Also checked for latest software update for the remote and it says it is the current one. Thanks for looking into this issue.

What happens if you connect the Stream box directly to your TV, bypassing the Soundbar?  

Thank you for the reply. I have not moved any equipment around. My soundbar sits directly below the TV and over the DTv device. The soundbar is connected to the TV audio output by a small fiber optic cable. When I went through the set up for my DTv remote, I selected my Polk Audio soundbar as my audio device and the remote control setting still reflects that choice in the Settings menu. The system has worked fine since Sept '21 and about 2-3 weeks ago, this sound issue  manifested itself. Thanks for troubleshooting the issue.

Have not tried that but will not be able to reply back to you until tomorrow when I initially turn the system on tomorrow as that is when the problem presents itself. Thanks.

Keep us posted. Connecting the Stream box directly to your TV will help determine if the problem is with the soundbar or somewhere else.
