Pandora MP3 Stuttering/Distorted, Local mp3's fine

After hours of troubleshooting, I'm posting for help as I think I've exhausted my ability to solve; using LMS v7.9.1 on x86_64 platform, connected to multiple RPi3 players running LibreELEC and Squeezelite v1.9.2-1165, outputting to HDMI. Local media mp3s play perfectly, FLAC files via Spotty play perfectly, but when streaming Pandora (mp3), somewhere about the 2nd or 3rd song, with about 1 minute remaining in the song, play starts stuttering. If I ignore it, the next song starts, plays fine until the 1-minute-remaining mark, and stuttering repeats. If I stop and restart the stream, first 1-2 songs play fine, then pattern repeats. I've tried adjusting squeezelite parameters (-a 200, or -a :8:32:) based on recommendations in other posts, to no avail. I set Pandora logging to Debug on the server and below is the error that posts when the stuttering starts, and it repeats at basically every stutter.

Slim::Networking::IO::Select::__ANON__ (131) Error: Select task failed calling Slim::Player::Source::__ANON__: illegal file descriptor or filehandle (either no attached file descriptor or illegal value): at /storage/downloads/lms/Slim/Networking/IO/Select.pm line 134.; fh=Slim::Plugin::Pandora::ProtocolHandler=GLOB(0xb e10cb8)

No other errors or warnings in the log, and yes this is a paid Pandora account, which streams perfectly to other devices on the same network via the native Pandora apps or a web browser.

Thanks in-advance to anyone with ideas and/or suggestions. Happy to research other questions or experiment with solutions and report back.
