    I've recently started to re-encode the audio when making h.264 mp4's of my dvd collection using AC3 Pass through via handbrake.

    These files (All are Dolby Digital 5.1) play perfectly on my laptop, Dune 101 and Dune Smart B1 but when played on the A-110 I get no sound. My A-110 and 101 are connected directly to a TV (no amp).

    All audio settings on the A-110 are set to Analogue PCM and HDMI audio is on and output is set to stereo. I've tried different settings but with no joy.

    I'm using the latest firmware for the PCH.

    Any help appreciated. Cheers.

    Wild guess but PCH A-110 may not support M4V files fully.

    The MP4 spec (M4V is just an Apple rename) originally debuted without AC3 support but the standard was updated to support it in response to Apple's AC3/M4V however not all players support the updated MP4 spec.

    Are the files with an actual .mp4 extension or .m4v extension, if they are .mp4 try renaming to .m4v

    Will give that a go later, thanks. Would it be better to make .mkv's?

    Yes use mkv container unless you need to maintain apple device compatibility, you can remux the m4v into mkv by using mkvmerge. In the mkvmerge options menu disable header removal (one time thing) to ensure compatibility with PCH-A110 as I'm not sure if it's firmware was updated to address that issue.

    No joy with the .m4v file type change :(. I was hoping I wouldn't have do another encode for these files but it's looking increasingly more likely. Would .mkv be better in future?
