[volenrog]

Tested on two systems (Win7)... in Windows 10 - Ok. Help!

Hello Volenrog and welcome to uos forum.

>Tested on two systems (Win7)... in Windows 10 - Ok. Help!

When does the crash appear, when you click on "Start" (record) button or "Stop" (record) or "Play saved file" button?
Do you get the crash when choosing to save as "ogg" or "wav" or both?

Do you get the same error when compiling with fpc 32 bit?

Did you use the last version of uos?

All variants from example.

FPC and Win7 - 64 bit ver

2023.03.03 from Lazarus Manager and from Github (v2240422)

Hello.

I need more infos to be able to help you because I dont have a Windows 7 machine to test.

So it seems that the crash comes at recording.
Did you try to load at init of program the older Portaudio.dll library that is in /uos/examples/lib/Windows/64bit/LibPortaudio-64old.dll ?

Did you try to debug the program, did you get a error message and what message?

Do you get crash also when running SimplePlayer demo, when choosing test.org or test.wav?

OK, but Windows 7 is multi-arch so it can also run 32 bit applications.
Did you try to compile+run simplerecorder demo using FPC 32 bit (and so the libraries 32 bit)?

Yep...

When select the option "wav" debugger show this info: <uos.pas>

On "ogg" this: <uos_libsndfile.pas>

No, it's ok.

No, my proj is 64 bit...

Hello.

Hum, it seems to have problem with the default device.

Could you give a screenshot of the result of the demo deviceinfos.lpi ?

Re-hello.

Do you have crash in the SimpleRecorder demo when "Save to file" is disabled (with "Listen to Mic" enabled/disabled) ?

[fredvs]

Thanks for the screenshot.

There is no default input device assigned in your screenshot.

Could you try to change in main_sr.pas at line 293:
In1Index := uos_AddFromDevIn(PlayerIndex1);  

with this:

 In1Index := uos_AddFromDevIn(PlayerIndex1, 6, -1, -1, -1, -1, -1, -1);
     
or this

 In1Index := uos_AddFromDevIn(PlayerIndex1, 7, -1, -1, -1, -1, -1, -1);

or this

 In1Index := uos_AddFromDevIn(PlayerIndex1, 9, -1, -1, -1, -1, -1, -1);

If "Listen MIC" and "Save to file" is disabled then it's ok!

I try 0 to 9... but still not work :(

[fredvs]

Hum, I dont have other idea at the moment.
Can you record something using the the native Windows recorder?

[fredvs]

It would be interesting to compile SimpleRecorder demo with FPC 32 bit and see if you get the same bad result.

It work

Okay, I'll try sometime...

[fredvs]

Maybe using a other release of Portaudio.dll?

There is some there:

Re-hello.

Maybe your Windows 7 has not defined the default input.
Here (maybe) some light (Audacity uses also Portaudio):

(I agree, lot of maybe...)
