Now recording playback works for me too (but without sound, of course).
Digital sound is produced if I give em8300setup -d command after vdr
start. I did some tests with mp3 plugin (are you using it?). The old bug
with 44.1 kHz audio seems to be present (can be avoided by setting use
always 48 kHz but it is not optimal for quality). Usually the first
track plays at correct speed/pitch. Successive tracks play incorrectly
at 48 kHz rate. It could be a bug in mp3 plugin as well. I tried to
enable debug output but I didnt't get any mp3 plugin originated rate
change messages into log.
