ISSUE: Sounds not playing


5 May 2018

Applies to

Older RC-Soar templates running in OpenTX 2.2


After upgrading to OpenTX 2.2, some sounds may not play even though though the files are present on the SD card.


This is due to a new 6-character limit for file names.

Note: sound files for all current RC-Soar templates satisfy the 6-character limit.


  1. Go to the Special Functions menu and make a list of all the sounds (.wav) files
  2. On the SD card, shorten the names of these files to 6 characters + '.wav'.
  3. Update references in the Special Functions menu.
