Hi. I have an USB soundcard connected to my laptop, to which I connected my headphones, with a microphone. Sound plays perfectly through the headphones, but the microphone doesn't work at all.

The two devices returned by ossinfo are:

Code: Select all

USB sound device play             /dev/oss/usb0d8c000e-1/pcm0  (device index 0)
USB sound device rec              /dev/oss/usb0d8c000e-2/pcmin0  (device index 1)

When I do:

Code: Select all

ossrecord -d /dev/oss/usb0d8c000e-2/pcmin0 -t 5 k.wav

This appears:

Code: Select all

/dev/oss/usb0d8c000e-2/pcmin0: Input/output error

What's the issue here? Thanks in advance.

USB soundcards are not supported. The USB driver is said to be "experimental".
Usually, the USB mic does not work, and the USB playback is not perfect (or it does not work at all).

So there is no way to have an USB microphone work at the present? Are there plans to implement it?

That "experimental" driver did work in 2009. It may never work.

You may get much better quality with the onboard codec and OSS4.
USB things might be useful with ALSA.

Does your onboard codec work with OSS4?
