Ubuntu - PulseAudio - reciever a perder a sincronização sempre

Question

Histórico:

Okay, so I have a receiver, an Onkyo TX-SR605. It's connected to my Ubuntu media machine with an HDMI cable from my motherboard a BIOSTAR Hi-Fi A85S3. Every time the receiver's input format changes, it makes an audible pop. Not a big deal most of the time, but on my Ubuntu install it's getting a bit insane. Every time sound starts or stops it makes that pop. Also, I lose the first half-second or so of the media, so it's making the media machine thing not work out so well.

O que tentei:

I've tried commenting the the line in defaults.pa that reads "load-module module-suspend-on-idle", and that works to a point, but it still switches a bunch when changing between 5.1 48khz and stereo 44.1khz audio. Most of the documentation for pulseaudio seems to be old and/or nonfunctional.

Minha pergunta:

How do I lock pulseaudio into sticking with 48kz, 5.1 sound?
No resyncing, no new formats, just stick with that one.

Se isso não for possível, há algo mais que eu possa fazer? Eu nunca tive nenhum problema no Windows 7, mas eu realmente não quero voltar a ele por causa de pops de áudio.

para dirkt:

Descobri que meu receptor pode fazer 192 Khz de forma confiável, então estou mudando para a taxa de amostragem.

/etc/asound.conf

pcm.StdOne {
    type plug
    slave {
            pcm "hw:0,3"
            format S32_LE
            channels 6
            rate 192000
    }  
}  

/etc/pulse/default.pa

load-module module-alsa-sink device=StdOne
load-module module-device-restore
load-module module-stream-restore
load-module module-card-restore
load-module module-augment-properties
load-module module-udev-detect
load-module module-native-protocol-unix
load-module module-rescue-streams

Ele ainda aparece e clica como nenhum outro. Obrigado pela tentativa!
