Sequences Played From SD Card on HinksPix PRO Controller Have Shuddering or Other Issues
SOLUTION: The following are requirements that must be met to ensure compatibility when playing sequences on the HinkspPix PRO:
- The SD card must be compatible with the HinksPix PRO, see this article on compatible SD cards: https://support.holidaycoro.com/portal/en/kb/articles/sd-card-not-reading-or-working-with-hinkspix-pro-cpu
- Make sure your SD card does not have read errors (see the debug tab in the HinksPix PRO web interface)
- The audio file must meet the following requirements:
- WAV or MP3 format
- If MP3 - Must be constant (CBR) and not variable bit rate (VBR)
- Stereo (not mono)
- Must have a sample rate of exactly 44100
- You can upload your audio file to https://www.metadata2go.com/view-metadata to determine the above
- sample_rate must equal 44100
- channel_mode must equal Joint Stereo
- lame_method must equal CBR
- If your audio file is not in this format, convert it to WAV file format using Audacity: https://github.com/audacity/audacity/releases/download/Audacity-3.7.7/audacity-win-3.7.7-64bit.exe (note that you do not need to install MUST Hub)
- Your firmware must be current, see https://support.holidaycoro.com/portal/en/kb/articles/updating-firmware-on-holidaycoro-hinkspix-pro-controllers-using-an-sd-card
- Your xLights version must be 2025.13 or higher, see https://xlights.org/releases/
- We recommend 50ms timing for your sequence, while lower timing maybe possible this will depend on the number of pixels controlled by the HinksPix and the model of your HinksPix.
- To determine what your timing is, open the sequence in xLights
- Go to FILE | Sequence Settings
- Look for 50 ms under the Info / Media tab

If your sequence meets all of the above requirements, perform the following steps to troubleshoot:
- Test only one sequence
- Play the sequence directly from the xLights Sequencer or xSchedule application to confirm that the root cause is not the base sequence
- Create a new sequence without music (Animation format instead of Musical Sequence) and another sequence with music
- Put only a basic effect on the props, do not import any sequence data
- Export to SD card and test
- If the non-audio sequence works correctly but the audio sequence does not work, this indicates there is an issue with the audio file (see compatibility requirements above)
- If both sequences (audio and non-audio) work correctly, the issue is with the original sequence as the test sequence works correctly
Information required for submission of a troubleshooting ticket:
- Copy of your test sequence
- Copy of your audio file for the test sequence
- Screenshot of the Debug tab in the web interface of the HinksPix PRO
- DO NOT send videos or photos of the problem occuring
