Comment 28 for bug 348353

Good news!

pl bossart also came up with a great way to avoid editing /usr/local/share/pulseaudio/alsa-mixer/profile-sets/default.conf

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

The args.0 will then allow a52:%f to match a52:0.

Luke, what can we put instead of "card NVidia"? "card 0" would work for the majority of users including me, but it would be nice to have something that will work if the card is not 0. Any suggestions?
