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