    I've searched around but haven't seen any posts with the same problem. Any help appreciated.

    Setup:
    -HR10-250 (installed 12/31), optical cable, McIntosh MX-132 receiver
    -Local channels through SAT, not OTA
    -Signal strength at 90s for 101 and 85 for 110

    Problem:
    1) Audio cuts out/blips out for 1-2 seconds and returns.
    -only noticed on Dolby 5.1 setting
    -Happens only on all the HD series of channels (HBO, HDNet, HDNet Movies, ABC, FOX, NBC, CBS, ESPN), though not necessarily HD broadcast (could be SD on HD channels)
    -Happens more frequently on ABC, FOX, NBC, CBS (10 times per hr?)
    -Happens on both live and recorded
    -On a live or recorded broadcast, does not blip out on the same spot, i.e., rewind and play and the audio is there

    2) Crackling noise
    -Only on HD channels
    -ProLogic setting
    This doesn't happen as frequently so I haven't had time to do as much troubleshooting

    One other variable is that I had a Samsung SIR-TS360 (non-tivo) prior to this and it would also have audio cutouts (I never spent time troubleshooting it since it was hardly used). I have 3 other SD Tivos in other rooms and all are perfect. Similary the SD broadcast channels on the HR10-250 are also perfect.

    In both cases, video is perfect.

    Any ideas?

    Thanks!

    I would first look at the McIntosh receiver. It may have a bad optical input or the optical cable is faulty.

    BTW, what are your signal strengths for 119 sat?

    101 - 93
    119 - 83
    110 - 87

    I don't think it's the optical cable or the port on the receiver. I'd swapped both the cable and the ports and tested with my DVD player.

    *bump*

    I guess I'm going to have to call the dtv techs out for some troubleshooting.

    Did you try a new cable?

    Yes, I did. I swapped the optical cable with my DVD player. also switched the ports going into the receiver as well.
