LMS 8.1 Radio & Boom have problems playing transcoded hires files (176.4khz & 192khz)

Radio stuttered & Boom sounded like 45RPM playing at 33.33RPM (ie. slow)

Logitech Media Server Version: 8.1.0 - 1608700893 @ Wed Dec 23 12:13:04 CET 2020
fell back to Logitech Media Server Version: 8.0.0 - 1605892076 @ Fri Nov 20 21:29:02 CET 2020

LMS running on DEBIAN, Beaglebone Black, file access via NFS from QNAP TS-251D

LMS 8.1 serving FLAC of 24bit 176.4khz & 192khz files
Bitrate: 5960kbps VBR (Converted to 705kbps FLAC)
Sample Rate: 192.0 kHz
Sample Size: 24Bits

LMS 8.1 serving FLAC of 24bit 96khz played okay
Bitrate: 2729kbps VBR (Converted to 705kbps FLAC)
Sample Rate: 96.0 kHz
Sample Size: 24Bits

Above are the same as I'm seeing with 8.0


things tried with 8.1.before falling back to 8.0
- installed LAME to see if Bitrate Limiting could be used as workaround
320bps mp3 worked fine but wasn't needed previously
- updated SOX and flac;
then copied SOX & flac to the LMS hard float directory to check for a possible dependency

Any ideas?

Shall I camp out on 8.0 until the transcode conversations subside?

Have you tried 8.1.1 nightly?

Best way to know exactly what is happening is to enable logging player.source to INFO and then look in log for the lines around the "TokenizedCommand" entry.

I have not tried 8.1.1 (yet ;-). Been watching nightly build Changelog for hints of transcode "fixes" "adjustments"
Fiddled with this from 3rd to 6th, need to enjoy some music.
R U suggesting there may be something that addresses my issue specifically, or just on general principles? Thanks you to philippe_44.

Thank you bpa, will keep in mind when I try nightly build (8.1.1?). I'll capture some 8.0 log to compare with nightly build if it has same issue.

Yes I fixed issue wrt to missing sample rate when transcoding which would exactly explain your case, I was not just shooting in the dark

THX philippe_44. Will try in a day or two.

I've just verified on a Boom with a 192/24 test file and it works fine

[JimmyG]

8.1.1 worked a treat.

Been transcoding hires files (176.4kHz & 192kHz) to Radio & Boom
