USB Audio - Issues with some Devices
Lars:
ok, had a look at the trace.
I assume that you asked for recording in both cases (which I am pretty certain is true).
What I can see already is that the system insists on calling the driver for "playback" which of course is wrong and also, as we know, the device cannot do "playback". No wonder it returns with an error (even though it correctly reports back that it can do "record").
Can you do me a favor and repeat this, including tracing, with the original 10.237 driver set ? I just want to know where we started initially.
If I have this picture I hopefully can find a hackaround.
Martin Iturbide:
Hi Lars
- On DTape I used. "Record Type -> PCM, 44100, 16bits, mono, microphone."
- For Audio Recorder I'm using "record /a2 /b16 /c1 /f44100".
I had tried back again with 10.237, I attach the trace.
What I did was:
- Boot, attach the mic, run lsusb to confirm it is attached.
- run Dtape - New ->Record, get the error. I repeated the record again on to get the error a second time.
later
- Command line, and do "record /a2 /b16 /c1 /f44100", get the error. Repeat the command to get the error a second time.
Regards
Lars:
ok, that's why the very same error appears twice (you run it twice).
So for RECORD, I assume that /b16 /c1 /f44100 mean 44100 Hz, 16 bits, mono just like you use for DTAPE, correct ?
What does /a2 mean ?
Lars:
ok, try attached. Also try with "playback + record" devices.
Take trace as you did before.
I ONLY updated USBAUDIO.SYS but not yet USBAUD2.SYS. Means, you need to test a audio class 1 device but I think you did. Make sure you do a full minstall as I had to update USBAUDIF.DLL along with the driver.
Lars:
Sorry, needed to update.
