Volume level, how to control it using a plist parameter

Recommended Posts

Hi all, I finally got my Sigmatel 9220 chipset working on Leopard. However, volume level is not loud enough. I need to set it above 50% just to be able to hear something.

 

I recall reading a post somewhere a couple of months ago that described a parameter in one of the AppleHDA.kext Info.plist files, that you can use to control the raw volume output. I've searched for about an hour and got nothing, because basically I have no idea of what exactly I'm looking for, and a search for "applehda volume" gets you an insane amount of results, but it was something like one of these (I may be totally wrong):

 

<key>InputSampleLatency</key>

<integer>30</integer>

<key>OutputSampleLatency</key>

<integer>30</integer>

<key>SampleOffsetPad</key>

<integer>0</integer>

 

I'd appreciate if somebody can give me a hint about this, thanks in advance!

would you please explain how you got your 9220 working?

 

I have a intel D945PSN and can't get the audio to work at all, I've tired all AppleHDApatches with .txt's but no dice.

 

i'm on the iATKOS 1.0i install.

 

intel D 820 2.8 D chip.
