I'd expect this to be with the rest of the initialisation for the structure that it's embedded in - having this be initialised in this place separately to anything else feels wrong. Of course at the minute it's not in a structure (which I raised as an issue as well IIRC) which means that we'll have an issue with multiple initialisation if two devices are registered. > > Are you sure that all the CODECs that rely on the existing shared > > register cache are going to call this? > What do you mean by 'shared register cache'?

Are you absolutely positive that every user of the code is using a register cache initialised using that method? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
