Si4713/Vast V-FMT212R - FPP 9.3-3 Skipping Music Sequences

[GeorgeK]

Running xLights 2025.11 and FPP on a Kulp Player Pi4 with SSD connected to a VASTINT-FMT212R. I noticed this sporadically when I updated to 9 in October for Halloween show. But the show would run as normal and then after a while it would run the tune-in animation (no audio) then it would play like 1 second of the beginning of each sequence before looping back to the beginning of the playlist to play the first tune in animation. Rebooting and sometimes restarting FPPD would see to take care of it, but only for one playlist playthrough. I started by updating and then again making sure my plugins are current. I am running Remote Falcon, FPP Remote Monitoring and the Si4173/Vast V-FMT212R. I checked error messages and was receiving the following in my syslog:

2025-12-01T17:24:47.379055-07:00 fpp kernel: [81146.568666] usb 1-1.4: current rate 8448 is different from the runtime rate 44100

Looking at lsusb I found that this was pointing at my VAST FM transmitter:

Bus 001 Device 004: ID 0451:2100 Texas Instruments, Inc. HiFi-FMT / VAST ELECTRONICS

As a result I went through downloaded my MP3s from the FPP and opened them in audacity and verified they were all CBR 192 kbps and that they were stereo 44.1kHZ sampling rate then re exported and uploaded into FPP. I then also renamed them and removed spaces. This seemed like it helped at times, but I was still consistently having issues with it. This started a few days before Halloween after applying an update to my FPP and my K16 controllers. I also changed the plugin settings for the VAST FM plugin to put the Plugin settings back to FPPD Start and then to stop Never. So far I can't get it to consistently play for more than 1 or 2 times. Any input is welcome and if I am posting in the wrong area please let me know where to post.

Thanks!

Updated to 2025.13 xLights. Saved again and reuploaded manually fseq files. Still had issue. Removed plugins still had same issue. I do have multiple Kulp Controllers running multisync if that is part of the issue. I downgraded my player to 9.2 and that seems to have resolved things. So it appears not to be an issue with the plugin but potentially with 9.3-3. I will keep my main player running 9.2 until I see an update or it gets resolved. 

Thanks.
