[Alsa-user] USB-no capture device

[Dennis B. <den...@go...>]

Hi list!

I just compiled the new alsa-driver, since I had no capture option with 
a Behringer UCA202 USB-card, which contains a PCM2902 from TI using alsa 
in version 1.0.20. Now, I recompiled the following packages:

alsa-driver-1.0.21
alsa-lib-1.0.21a
alsa-utils-1.0.21
alsa-firmware-1.0.20
alsa-plugins-1.0.21

Then I copied them to a flash-card, that is put onto an ALIX-board from 
PC Engines. In the BIOS of the ALIX, I disabled the on-board CS5535 and 
then I plugged in the USB-card from Berhinger and did a full reboot. Now 
the result is the following:

#alsactl store
# cat /etc/asound.state
state.default {
    control.1 {
        comment.access 'read write'
        comment.type BOOLEAN
        comment.count 1
        iface MIXER
        name 'PCM Playback Switch'
        value true
    }
    control.2 {
        comment.access 'read write'
        comment.type INTEGER
        comment.count 2
        comment.range '0 - 128'
        comment.dbmin 0
        comment.dbmax 0
        iface MIXER
        name 'PCM Playback Volume'
        value.0 128
        value.1 128
    }
}

So far, so good, but if I go to alsamixer and try to select a capture 
device, it shows the following:

This sound device does not have any capture controls.

What am I doing wrong? Any ideas?

I hope for a good answer since I want to get this device running :-)

Kind regards,
Dennis
