Hello,
Sorry, if this is wrong group, butb I do not know where to post
this.
I have just installed AOpen FM-56 P internal (PCI) voice modem.in Windows
XP.
The installation added Unimodem Full-Duplex Audio Device line in Device
Manager under Sound label.
However, when I go to Control Panel>Sounds and Audio Devices there are not
any references to it.
Also, in my code lineGetID() with "wave/in" or "wave/out" returns error:
LINEERR_NODEVICE (0x80000042)

But, when I use Tapi Browser20,
lineGetID() with "wave/in" or "wave/out" returns SUCCESS

Why Windows and my code cannot see the modem's playback devices?
I should mention, that my code works fine with other voice modems, which
have properly displayed playback devices in Control Panel>Sounds and Audio
Devices
Where can be the difference?
There is not a difference in lineGetID() Params between TB and my code.

Please see the TB log below.

Correction:
Now, TB also shows the same error. (I used wrong line ID that why
lineGetID() returned success).
lineGetID returned LINEERR_NODEVICE
Please see the correct log below:

==========================
lineInitialize returned SUCCESS
num line devs = 7
lineOpen returned SUCCESS
lineGetID returned LINEERR_NODEVICE
===========================

Thanks,
Claire

You may want to check Andreas's answer to my question earlier:

I seem to have the same problem with my modem on Windows 7. It's not
listed in Control Panel , Sound. But on an XP pro machine, it shows up
all right.

No, your problem is different.
My modem installs unimodem and it is listed in Device Manager under Sound
label.
The problem is it is not responding to lineGetID().
I wonder if it is possible to change that by possibly editing the inf file?

My modem *is* listed in "Device Manager" under "Sound" as "Unimodem
Full-duplex Audio Device". But it does not show up as a playback device
in "Control Panel", "Sound". This is not the case with XP pro, so I
guest it's a driver/inf problem. Playing with the INF file is over my
head. If you figure it out, please let me know.

Thank you Andreas,
There are not modem's audio devices included, but please notice that Device
Manager shows Unimodem Full-Duplex Audio Device.

So it seems that there is something wrong with the modem installation.

Did you already try to re-install and check the manufacturer's website for
updated drivers?
