Hi,
I have a PC that just has its own internal sound card, nothing special.
However, this card (HDA Intel) has three output ports: analogue, HDMI
and optical.
I have been trying to find a way to get output on both the analogue and
HDMI ports at the same time. I have succeeded, but had to use command
line/default.pa to do this because of how sinks appear to be configured.
My understanding is as follows:
1. When using pavucontrol or the Ubuntu sound settings, you can see
the card under Output Devices.
2. The drop down list is a set of ports for this sound card.
3. Only one port can be set at a time.
I've also noticed that "pavcmd list-sinks" only ever lists one sink.
When a port is changed using pavucontrol, there is still just one sink
available, but it's a different port and different index.
So if only one sink is ever available, I cannot create a new combine
sink, whether using the command line or paprefs, as it will just create
a combine sink on the one sink, which is pointless.
My questions are:
1. When setting a new port using the GUI, is the old sink module
unloaded, and the new one for the new port loaded?
2. Why? I would have expected there to be a sink for each port, and
just the default configured via the GUI, but this doesn't appear to be
the case.
Many thanks,
Marc
