Hello,
While discussion on how we should deal with hardware with different
requirements from standard desktop cases continues, I'd like to solve the
problem of having modem PCMs that we don't want to auto-suspend in the near
future. For this, I've attached a couple of patches that allow a sink or source
to be flagged as "always running" which would cause suspend to be avoided if
possible.
Any objections?
Yes. 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.
