Hello. Is there any cli utility to set AHI volume *only*?

Best of all if it had freely available C sources...

thank you and regards

p.bes

Retry.

This is a help request to current Amiga developers. Unluckily I do not have the skill to do this by myself, but I guess many of you are. I'd need a simple utility in C to change the sound volume with AHI. A quick implementation of it would just change the 'main' volume, from 0 to 100%, for all the available music and audio units. Would anyone volounteer? Requisites: being open source and straight-to-compile on any Amiganoid system and platform.

My intermediate goal is just having the cance to open a shell window and give a command like

ahivolume 0 --> to set the overall sound volume to null
ahivolume 100 --> to set the overall sound volume to max

and obviously any intermediate value in the range 0-100, independently from the physical device used for sound (it shall work with any audio driver / audio mode).

Is this feasible? Or are ther technical problems making it a complete mess? Thank you.



The final (longer term) goal will be, at least on Icaros Desktop, writing a simple lua-based GUI with a slider, a mute and a setting button, but I should be able to do this by myself.

Just a thought, does AHI have an Arexx port ? if so, it should be really easy.

Mixer has an ARexx port and an ARexx command for setting the master volume.

@jap

Thanks. Unluckily AROS and Arexx don't sound well together.

But if someone can tell me what are and how to use these commands, I may try to learn and use them.

In the section “Other examples” there’s a “Master volume utility” that might be usable? Given the URL it should work for AROS.

Hi joakim, first of all thank you so much for pointing me into the right direction. According to the description, the program should almost do what I need, but unluckily I am no coder at all, and since the building process with gcc produces more than 10 errors (due to unknown types, undeclared identifiers and variables), there is very little I can do by myself but learning C, which is not exactly the kind of task I can complete in a few days while at work for my regular job.

So, I am nearer to a solution but still stuck into my coding ignorance. And I still need help from the community.

@paolone

Why not contact AROS developers more directly?

@kolla

That wouldn't help much, because the code listing there is not for this "Master volume utility", but a copy of the AHI sound code from one of Bigfoot's Quake engine ports.

Someone can starts from here:

http://www.os4depot.net/index.php?function=showcontent&file=audio/misc/mixersource.lha

this is the mixer source code of OS4. There is for sure the master volume code

Seen that and already proposed on aros-exec.


@Kolla

Done that, but I posted here and on facebook's Amiga group to reach a wider audience.


I am keeping track of all the discussions about this. Thank you.

@paolone

Hi, Paolo

Inside the archive there's Arexx.c source code; it contains volumeDown, volumeUp functions. Both functions call first vol=GetMixVolume(id)-StepSize; (or vol=GetMixVolume(id)+StepSize) then SetVolumeQuietly(id,vol).

This should do the trick.
