Title: AUDIO: device does it work at all?
Post by: aGGreSSor on November 17, 2021, 12:27:40 AM
I can't find the following files in the existing AROS builds:


Judging by the comments of the commits, they were moved to the core. OK!
I'm create a file DEVS:DosDrivers/AUDIO

Code: [Select]
Handler=AHI-Handler
Stacksize=4096
Priority=5
GlobVec= -1

Then I execute the command:
Code: [Select]
1.AROS> mount AUDIO:
Mount failure
ERROR: Object is exist!

Wonderful! Next command:
Code: [Select]
1.AROS> copy suprise.wav AUDIO:
Not copied - device is not mounted
WHAT?!

Original AHI AUDIO: supports Audio IFF and AIFF Compressed (AIFC) including Linear PCM (both big-endian and little-endian)
We know from the documentation for AHI Users (http://www.lysator.liu.se/ahi/v4-site/files/ahi/doc/ahiusr_15.html).
The AROS documentation states that this is also supported (https://en.wikibooks.org/wiki/Aros/Developer/AHIDrivers#Other_Examples).

What am I doing wrong?

This is normal because if the AUDIO DosDriver is in DEVS/DosDrivers it is mounted automatically.
If you want to mount AUDIO from a Shell you have to copy the AUDIO DosDriver in Storage/DosDrivers

I don't think you're doing anything wrong, on AfA One the command works only noise is heard

Then that's a big problem. For Amiga there is a large number application for which doesn't bother working with AHI, but simply sends PCM in AUDIO: (similar to the copy command from CLI), because it's a much simpler interface. In addition, it allows you to make cross-platform applications outputting sound for Amiga similarly to output for other OS. If that only noise is heard, then it's understandable why sounding apps for AROS are so few...

I enclose a small Viudeo Test on OS3.9 BB4, same result as AfA One !

Darkness. Files in the AIFF format are played by this method?
You can get an AIFF-file from MP3 under OS3.9 using mpdecode (http://aminet.net/package/mus/edit/mpdecode).

Tried mpdecode on OS 3.9 BB4 AfA One and the MP3/AIFF conversion works perfectly, I attach an exhaustive video!
