Does that mean the original question was not about virtual sinks but about the null sink? The null sink is not counted as a virtual sink and the patch I sent is useless in that case. The null sinks could however be excluded in module-switch-on-connect by a similar approach. I guess it would also be possible to set some "do-not-use-as-default" property on a sink that could be parsed by the default sink selection process, but that would not only affect module-switch-on-connect but would also need to be considered in the core. > > On Sat, Nov 11, 2017 at 10:03 AM, Ð?иÑ?аил Ð?овоÑ?елов, Ð?Ñ?малогиÑ? > <mikhailnov at dumalogiya.ru <mailto:mikhailnov at dumalogiya.ru>> wrote: > > Yes, of course, it's possible to unload module-switch-on-connect, > but that is breaking the existimg user setup. > "a command line switch could be added > to the module so that it ignores virtual sinks" Will be best.
