My new Bolt Experience 4 diagnostics: Latest firmware 7508.11.0 Firmware upgrade status: Unknown Pairing status: Not paired Pairing ID: Unknown Remote address: 0 Total paired remotes: 0 I paired the remote & cleared both the remote and DVR several times (rebooting everything.) Microphone finally worked. The Bolt seems to not have any problems, everything works. I connected a Zvox hearing enabled sound bar that is not listed with codes for Tivo. It recognizes Tivo remote commands for vol-up, down, mute, and power off. This worked without a problem on the living room Bolt+ but not with this new Bolt. I had to temporarily put the remote in IR (red flash) mode and then it only recognized up down sound. If the diagnostics are right there may be a bolt dvr pairing problem. For comparison I cleared & paired my Bolt+ remote with the new Bolt 4 and it made no difference.
