Yes. Most of the time there's some sort of forward compatibility, but not this time (doing so would be too complicated/risky). Sorry. So, the safe upgrade order remains: kernel, libraries, sndiod, clients. That's because lower layers provide backwards compatible interfaces to upper layers. > By the way, remote playback the other way round (from the 7.9 server to > the 8.0-current laptop) works as expected.
