[pulseaudio-discuss] {PATCH][RFC] AC3 passthrough support

[Michael Rans]

You're welcome.

This may be an obvious question, but what is the 
@args.0 {
    type integer
    }
for?


Is that what you meant by "Adding the argument removes the need to exit the 
profile." and if you did, I didn't understand at what point I had to exit the 
profile. Can you explain? Sorry if I'm being stupid.

Cheers,
Mike

Actually discard this comment, it looks like it's crunching data if
you specify the rate in asound.conf.

# Encode AC3 -> Directly on hardware
pcm.Filter_A52Encode {
    type a52
    bitrate 448
    channels 6
}

# Rate Converter to 48kHz, needed for some applications
pcm.a52 {
    @args.0 {
    type integer
    }
    type rate
    slave {
        pcm "Filter_A52Encode"
        rate 48000
    }
}

Adding the argument removes the need to exit the profile.
It's really odd that the rate plugin is required even though
everything is already configured at 48kHz.
I will test tomorrow and if this is fine then I'll prepare a patch for
upstream. Thanks for doing the groundwork for this bug.
