Is there any alternative for sound decoder? Is it possible to run sound file on JMRI PC instead of the on-board sound decoder? The PC speaker should be used for the sound in that case.
No. Read the below link. Store it in Favorites. http://jmri.sourceforge.net/ You can buy the SurroundTraxx from SoundTraxx. Quite pricey. You can probably download sounds to your PC from the decdoer sites that will allow this. Connect up your own sound system. Rich
