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
}
}
#cat /proc/asound/cards

P0-0-1: PCM capture 0-0-1 : SLAVE
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
