# blast: tunnel audio from a pulseaudio sink to a UPnP/DLNA device (like a TV).
|
|
# - expect 7s of latency
|
|
# - can cast the default sink, or create a new one "blast.monitor"
|
|
# and either assign that to default or assign apps to it.
|
|
# compatibility:
|
|
# - there is no single invocation which will be compatible with all known devices.

# - sony tv:
|
|
# - `blast` (default): WORKS
|

# - `-usewav`: FAILS
|

# - LG TV:
|
|
# - `-usewav`: WORKS!
