USB Audio - Issues with some Devices

<< < (4/7) > >>

Martin Iturbide:
Thanks Lars.

I had de-installed USBAudio with "minstall" first. Rebooted and installed your drivers with "minstall" again, all the 4 packaged included and rebooted. I'm using ArcaOS 5.0.6.

To test, first I tried the "HP Gaming Headset H320GS" which was working before and I confirmed it still records audio with its USB mic with DTAPE. With this I guess the USBAUDIO driver is installed correctly since it worked.

Now I tried the USB Mic first: C-Media Electronics USB Mic (0D8C:013C). It did not work.

First I tried a lsusb just to be sure it is recognized.

--- Code: ---[X:\]lsusb
Bus 001 Device 001: ID 046d:c077 Logitech, Inc. M105 Optical Mouse
Bus 001 Device 002: ID 05c8:0317 Cheng Uei Precision Industry Co., Ltd (Foxlink)
Bus 001 Device 003: ID 147e:1002 Upek Biometric Touchchip/Touchstrip Fingerprint Sensor
Bus 001 Device 004: ID 0d8c:013c C-Media Electronics, Inc. CM108 Audio Controller

--- End code ---

Later I used DTAPE to test with the same settings that I used "HP Gaming Headset H320GS". The program gives me a "Hardware Error".

I also tried "Audio Recorder" and I got a similar hardware error.

Regards

Lars:
Try this.

Lars:
If it still does not work, I'd need you to activate tracing for major code 238.
How this is done is described in the readusb.txt. I would need a formatted trace. That will hopefully tell me enough about what is going wrong so that I can fix it.

Martin Iturbide:
Hi Lars

I followed the instructions.

- Added these on the config.sys.

--- Code: ---TRACEBUF=2048 /M=W,Q,NODTI /D=ALL
TRACE=ON 238

--- End code ---
- Rebooted, Attached the USB mic C-Media Electronics USB Mic (0D8C:013C).
- Executed DTAPE, produced the Hardware error twice
- Executed record.exe and produced the Hardware error twice
- Saved the .ftf file as formatted.

I hope it can give some hints.
Regards

Lars:
What sampling rate,num channels, bit depth did you select ? Did you indeed select record ?
Did you do the same as the screen shot you posted ?
I need to know this so that I know if the app request matches to what is requested from the driver or not.
As I said, the multimedia subsystem is a mess.
