bose TV sound bar compatability

After installing a Bose TV sound bar (using optical cable) my Xfinity X1 remote suddenly can't perform any TV functions (power, TV speaker control, etc.) but the cable box/voice functionality seem OK.  The only way I can fix this unplugging the TV, removing the sound bar, and plugging the TV back in. Then the remote works just fine; works as before. Is there a fix for this? Please don't spend 100 words thanking me for reaching out, just give me a solution. If there isn't one, just let me know so I can return this. It's an Xfinity issue, not a Bose issue. Thanks.
