Hi,
After I click on Apply button the Alsa Device Configuration section
become enabled, but when I specify hw1,0 in Stereo text field and play
a song amarok shows the message: "Audio output unavailable; the device
is busy.".
/proc/asound/ # ls
ASM5X0 Modem card1 cards hwdep oss seq version
ICH6 card0 card2 devices modules pcm timers
the file ASM5X0 is a symbolic link to card2.
/proc/asound/ # cat cards
0 [ICH6 ]: ICH4 - Intel ICH6
Intel ICH6 with unknown codec at 0xc8000800, irq 18
1 [Modem ]: ICH-MODEM - Intel ICH6 Modem
Intel ICH6 Modem at 0x3400, irq 18
2 [ASM5X0 ]: USB-Audio - AS-M5X0
Gradiente AS-M5X0 at usb-0000:00:1d.1-1, full speed
I also tried to specify hw2,0 but the message is the same, device is busy! :(
But a good news is that if I do:
mpg123 -a /dev/sound/dsp1 music.mp3
... the file is played on my usb device perfectly!!! So, this is the
proof that kernel recognize the device and I just don't know how
switch alsa default device do /dev/sound/dsp1.
Any clue? Thank you,
Leandro.

Hi... The device is configured and I type cat xxx > /dev/sound/dsp1
and I got an strange sound, but this prove that the device was
recognized by the kernel. I also can control volume of the second
audio device through alsamixer. The question is: how can I specify (on
alsa) that the default device is /dev/sound/dsp1 or something like
that?
I tried to do what you said on Amarok, but the "Alsa Device
Configuration" section is disabled, why?

Leandro.
