Hey guys.

I have some problems with Mixer which i have never seen before.

I have mixer in wbstartup prefst and it plays sound on boot as normal but everytime i start an app or game etc then i have to open up mixer and adjust one of the sliders just to be able to get sound.

anyway, decided to check here to hear if anyone have an idea to what the reason for this might be.

Mixer 1.30 , OS4 update 4.

What sound card do you have?

This is because AHI always resets the volume to what you saved in AHI prefs everytime a new sound plays. There is no connection between the Mixer and AHI. They don't know about each other. They both hack the sound-chip individually and independently.

I made a little tool to prevent this. I called it KeepAHIOpen and it opens an AHI channel but doesn't play sound on it. However, this prevents AHI from resetting the volume everytime a new sound starts so the Mixer can actually be used properly. The drawback is that you can't switch modes from for example analog to digital output by using another AHI unit, or change playback frequency by using another unit without quitting KeepAHIOpen first. I have KeepAHIOpen in my startup-sequence.

Did I mention that AHI is pretty badly designed for todays needs..?

Maybe I should upload this tool somewhere.

The cause seem to be that the driver resets the volume before playback, I'd have to modify the Emu10Kx driver to make it save/restore the previous volume settings and there may be a reason why it doesn't do this already.
I'll have to ponder on this one for a while

hmmm , i messed around abit now and now TuneNet doesn't require me to mess with Mixer to get sound.

AHI mode in TuneNet is now : Ahi UserMode.

@AlexC

This happens with the cmi8738-driver as well.

I think AHI should always remember the last set volume, for each unit. So if another app is playing on a different unit that unit's volume (being default if the first time) should be used.

@Toaks

You should set a default volume for your units in the AHI prefs. I found that -30.0 or -35.0 is a good starting point. Kind of in the middle of the range. I think default is either 0.0 (max) or some minimum value.

I see what you mean about keeping a channel open for AHI.

I was able to test this by starting PlayCD and Pausing it then starting
Timidity. AFAIK Timidity uses the Music unit in AHI and is somehow connected
to Unit 0. I guess PlayCD uses Unit 0?

Anyway, I have one MIDI tune that produces an extreamly loud SNAP when started
but does not do that when using this proceedure. And, it also solved(?) the
problem of having to mess with the mixer.

While goofing around with this I noticed Mplayer would not produce sound
but DVplayer would.


Nice catch. Good info.
