6. Common issues and fixes

• Audio channels missing or silence: Open audio track selection; if AC3 passthrough causes silence on some devices, enable stereo downmix or switch to a different audio renderer.
• Subtitle not showing: Ensure subtitle track enabled; if external SRT exists, rename to match filename and load. For styling issues, use .ass with embedded fonts or copy font attachments from MKV.
• Choppy playback on low-powered device: Enable hardware decoding (VA-API, DXVA, NVDEC), lower output scaling, or transcode to lower bitrate.
• Out-of-sync A/V: Try switching to alternate frame timings in player, or remux with corrected timestamps using ffmpeg:

  ffmpeg -i in.mkv -c copy -map 0 -avoid_negative_ts 1 out_fixed.mkv
  

• Corrupted file segments: Attempt remux or re-download. ffmpeg can try to salvage:

  ffmpeg -err_detect ignore_err -i in.mkv -c copy out_repair.mkv
