Hi to all,
I have a strange issue connecting an usb audio device on my Omega2+. If I connect the usb audio directly to usb port of the Onion it works fine. But I need a webcam too, so I connect the webcam and the usb audio card via a usb hub. The webcam works fine and the also the usb audio works (if I reproduce music, talk or white noise), but if I play a continuous tone (for example 500 Hz), the audio pops!
If I connect the audio device directly to the usb port (without the hub), it works fine also for the tone.
It doesn't matter the codec sample rate (I tried 8 khz, 16 khz and 32 khz) or if the webcam is present or not.

Thanks
Maurizio Messa

Thanks bill,
I changed the Omega with another one (just removed from the box, with build b201) but the result is the same.
To solve the problem (I NEED audio) I connected an USB audio card. In this case the playback is very good, but the recorded audio is bad.. The sound is very disturbed (there is a background clatter), also changing the microphone.
Someone has experience with usb audio?
Thanks
Maurizio

@William-Scott
Thanks William, I didn't think to connect the serial console (the ssh console crashes without any message). I will do as soon as possible.

Good morning to all,
I need audio on my Omega2+, so I connected a MAX98090 chip to it. The operating system recognize it, but, after enabling i2s with the omega2-ctrl command, when I try to use it (for example with aplay), the entire system crashes and I need to switch off and on.
I tried different build version (B200, B232, B193,B180...) but the result is the same.

Please can some one help me?
