The difficulty here is of course that while the server throws an error, you're looking to fix the client side, because there won't be a maintainance release of the 0.9.15 series anymore. If you can install debug symbols, you can set a breakpoint at protocol_error(). This will break in command_stat() (src/pulsecore/protocol-native.c), right after the !pa_tagstruct_eof(t) check. There you can inspect what kind of unexpected extra data is in the tagstruct and take it from there. Please also try whether other commands work. Maarten
