Hello!
I'm slowly plodding along on my multi-zone system. It's a lot easier to
use names like "zone1" than "alsa_output.pci_8086_2668_alsa_playback_0",
so I'm remapping the modules in default.pa. It also gives me just a
single location with hardware-specific names, which works well. I'm using
the following command:
load-module module-remap-sink sink_name=zone1
master=alsa_output.pci_8086_2445_sound_card_0_alsa_playback_0 channels=2
master_channel_map=front-left,front-right
channel_map=front-left,front-right
The only disadvantage of this that I can see is that pavucontrol shows
both sinks when you go to move a stream to a different sink, and the name
of the remapped sink is not very helpful:
Intel 82801BA-ICH2 - Intel 82801BA-ICH2
Remapped Intel 82801BA-ICH2 - Intel 82801BA-ICH2
Especially for now, I can live with it, but is it possible to control the
device.description of a remapped sink?
Also, while I'm asking, are there disadvantages (especially performance)
to remapping a sink like this? For example, in comparing the sink
information between the original and remapped sink, it seems that the
remapped sink does not have HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL like the
original sink does. Will this affect CPU usage or audio quality?
Finally, my last question is this: is there a way to control the actual
name and description given to the original sink? Especially in the
short-term, I don't mind having to statically configure the devices in,
say, default.pa, even if that means I can't hot-plug new devices. I would
certainly do this if there are CPU or quality advantages to not doing the
module-remap-sink.
Thank you very much for your thoughts! I appreciate your help.
