R3 Directv remote will not mute bose lifestyle ultra soundbar

I am  not familiar with your devices, but Google Gemini AI told me this info below.  I'm not an expert.  Just trying to help.

This is a frustrating and surprisingly common glitch. The DirecTV Gemini remote and the Bose Smart Ultra Soundbar have notorious communication issues. Because the Gemini remote lacks "IR pacing" adjustments, it often sends commands too fast or doubles them. When you hit mute, the remote is likely sending a rapid-fire "Mute/Unmute" double command, or your TV's HDMI-CEC is instantly overriding the command and waking the soundbar back up.

Since resetting the remote didn't work, let's look at the three most effective workarounds to fix this loop.

Method 1: Offload Audio Routing to the TV (Recommended)

Instead of forcing the Gemini remote to talk directly to the Bose Soundbar, program the remote to control your TV's audio, and let the TV pass that mute command to the soundbar via your HDMI-eARC cable.

1. On your Gemini remote, press the Home button.

2. Go to Settings > System > Remote & Devices > Program Your Remote.

3. Select Advanced Remote Program > Switch Volume Control.

4. Change the target from the Bose Speaker/Soundbar to your TV brand.

5. Test the mute button.

Method 2: Adjust HDMI-CEC "Power Sync" on the Bose App

Sometimes the soundbar unmutes because the TV sends an instantaneous "wake up" signal over the HDMI cable the second the audio drops.

1. Open the Bose Music App on your phone or tablet.

2. Select your Smart Ultra Soundbar.

3. Go to Settings > Advanced > HDMI-CEC.

4. If it is set to Default, try switching it to Alternative or Off (Option 3/Option 4 depending on the app version). This prevents the TV from fighting the remote for control of the soundbar's state.

Method 3: The "Hold" Trick

Because the issue is often caused by the remote sending a rapid double-signal on a quick click, many users find that changing how they press the button stops the behavior.

• Instead of a quick tap on the Mute button, press and hold it down for a solid second before releasing.

• Alternatively, try a rapid double-tap.

If none of these software handshakes stop the glitch, it means the Gemini firmware is still stubbornly sending a corrupted IR command to that specific Bose model. In that scenario, your best bet is to rely on your TV's original remote or the Bose app for muting until DirecTV patches the IR repetition rate on the Gemini device.
