Hi... just to document. There are two options: 1) I created ~/.asoundrc file (as suggested by Richard) but with some modification as shown next (I don't know if all this option is necessary, but the sound is perfect):
----- ~/.asoundrc pcm.card0 { type hw card 1 } pcm.!default { type plug slave.pcm "dmixer" } pcm.!output { type dmix ipc_key 1024 ipc_key_add_uid 1 slave { pcm "card0" period_time 0 period_size 1024 buffer_size 8192 rate 192000 } bindings { 0 0 1 1 } } pcm.!input { type dsnoop ipc_key 28889 ipc_key_add_uid 1 slave { pcm "card0" channels 2 period_time 0 period_size 1024 rate 192000 } pcm.!duplex { type asym playback.pcm "output" capture.pcm "input" } pcm.!default { type plug slave.pcm "duplex" } pcm.dsp0 { type plug slave.pcm "duplex" } ctl.mixer0 { type hw card 0 } pcm.jackplug { type plug slave { pcm "jack" } } pcm.jack { type jack playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_2 } } 2) change alsa configuration module to put my card1 to card0 and card0 to card1 (don't forget to restart alsa daemon): ------ /etc/modules.d/alsa alias /dev/mixer snd-mixer-oss alias /dev/dsp snd-pcm-oss alias /dev/midi snd-seq-oss alias snd-card-0 snd-usb-audio alias sound-slot-0 snd-usb-audio alias snd-card-1 snd-intel8x0 alias sound-slot-1 snd-intel8x0 options snd-usb-audio index=0 options snd-intel8x0 index=1 ------------------------------------ ... snd-intel8x0 is the module alias for my internal sound card and snd-usb-audio for my external usb audio device. BTW, thanks Richard. []s Leandro. -- Leandro Melo de Sales.

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. 2006/10/31, Leandro Melo de Sales <[EMAIL PROTECTED]>: > Hi...
