[Iaxclient-devel] Setting output level on windows

[Cyril V. <cyr...@me...>]

	While evaluating iaxclient, I noticed a small bug in px_win_wmme.c line 735 
(_Px_InitOutputVolumeControls). 

mixerOpen( 
		( LPHMIXER )( &mixer->hInputMixer ), 
		hWaveOut, 0, 0,
		MIXER_OBJECTF_HWAVEOUT 
	) ;


should be 

mixerOpen( 
		( LPHMIXER )( &mixer->hOutputMixer ), 
		hWaveOut, 0, 0,
		MIXER_OBJECTF_HWAVEOUT 
	) ;


	the cirrent code does not set the output volume of the right interface (in the 
case the current device is not the first one)


Regarding thread priority, it is better to set the thread priority directly. On 
windows, scheduling is done thread by thread and SetPriorityClass influence 
every thread in a process which is not good. It would be better to replace

	SetPriorityClass

by 

	SetThreadPriority(GetCurrentThread(),THREAD_PRIORITY_TIME_CRITICAL)

this will only change the priority of the thread servicing audio and not any 
other threads (user interface ...)


Is there any plan ta support Alaw (I'm in france, and it's the native pstn 
codec here) ? I've hacked some support base on asterisk code, but there might 
be licencing issues.
