Pro Audio profile causes audio.channel = "UNK" in the card ports
Today I've noticed that I could not link a pw_filter to the sound card when the Pro Audio profile was selected. After some investigation I found out that in this profile the card ports do not report their channel name
audio.channel = "UNK"
Is that by design or a bug? At this moment I am relying on the channel name to know if the port is front-left or front-right. Is reading the
audio.channel value the proper way to get this information or should I be using something else?
