These devices are used to open connections to modems without receiving any data from userspace. I don't think PulseAudio should flag specific sinks this way, somehow the information should be available at the ALSA level that such devices do not provide/expect any data and should not be suspended. This information is available at the kernel level (no_pcm flag or something), it should be made available to user-space. -Pierre
