Those of you who had problems with recording, which audio card / driver you are using?

I'm using HD Audio and noticed that I have to choose 16-bit recording from HDMixer, otherwise DoIO() gets stuck. Not sure how to deal with this on SDL side when using the AHI device API.

I have the same issue with AHI's Device API RecordTest. DoIO gets stuck, unless 16-bit recording is forced.

Could you please check it?

@Capehill

I have selected a 16-bit mode for all AHI units, but sadly the program still stops responding in the Sampler section as soon as I press the "Exit" button (any of the two). Interestingly, the other buttons in the Sampler section work (until I press Exit).

@trixie

I meant if you could test AHI (device API) recording example, it should part of the SDK. I can put a binary online too, if needed, it gave some compiling error out-of-box.

If you had some problems with recording, please could you try this example and check whether it can get past "Before DoIO" log. Thanks.

@Capehill

Executing a.out just opens an output window that says "Before DoIO" and that's all.

@trixie

Thanks for confirming AHI issue. I don't know if there is anyone who could investigate, especially if it's a driver side bug.

There was another AHI issue about playback noise in 8ch mode.

@Capehill

Do you find what bug are with recording ? I meet today myself with : if i have 32bit set in ahi prefs, then even if in the app i myself choose 16 bit or whatever, the CMD_READ always stuck and returns nothing ever. Once i change in ahi prefs both default unit and unit 0 to 16 bit, recording works.

The low-level case via AHIA_RecordFunc etc works with both 16 and 32 bits sets in ahi prefs, its the device interface way works only with 16 bit prefs set. Quite strange..

No. If https://github.com/mheyer32/AHI compiles for AmigaOS 4, then maybe something can be tested. But drivers are closed, so it may be a dead-end.

It compiles for os3 and morphos, and surely can be compiled for os4 too with some small changes, but is it "official" ahi6 from original author ? He open sourced it ?

But then it can be AHI itself acts, and drivers OK ? At least, how we can explain then, that Low-Level interface works in any mode , while device level only with 16bit ?

@kas1e

AHI is open source, but I don't know if this repo contains all OS4 changes.

https://github.com/mheyer32/AHI/blob/BRANCH_6/Device/device.c#L1045 well this looks worrying, it signals only on 16-bit type?

Quote:AHI was open source, incl. all AmigaOS 4.x parts, as part of the ARP2 project but the official sources from the original AHI author were hosted on the https://en.wikipedia.org/wiki/BerliOS SVN which was shut down more than 10 years ago already.

I don't know if the github sources of AHI are based on it, or if it's something different and/or incomplete.

Edit: Looks like most of the BerliOS ARP2 project was mirrored on https://sourceforge.net/projects/arp2/ by Martin Blom, even parts (not sure if it's complete and/or the latest versions) of my RDesktop AmigaOS 4.x port, which was hosted on BerliOS as well, are included.
