[alsa-devel] problem while reading the data from device(phone)

[Susovan Ghosh]

Hi All,
       We are using ALSA for a application.We have a phone and RJ11 phone
adaptor-duel.I connect the phone to PC through the adaptor amd use the ALSA
function snd_pcm_readi() to capture what ever spoke in the phone.Adapter is
a USB device.we mention "plughw:0,0" as a capture device.When we run the
program we get an error "device is unavailable ".what may be the problem? or
de we required any thing more?

Thanx,
