Hi,

sorry for a bit helpless question but I couldn't find
the answer in the handbook and in the "man psm" myself.

I have put "device pcm" into my kernel config and compiled it.
Since I use FreeBSD 5.1, I haven't run MAKEDEV. Now I have:

newhope:mpg321 {564} dmesg | grep pcm
pcm0: <CMedia CMI8738> port 0xd400-0xd4ff at device 14.0 on pci0
pcm1: <VIA VT8235> port 0xe000-0xe0ff irq 9 at device 17.5 on pci0
pcm1: <Avance Logic ALC650 AC97 Codec>

Also I have different dsp* devices, but no /dev/dsp:

newhope:mpg321 {565} ll /dev/dsp*
crw-rw-rw-  1 root  wheel   30,   3 Aug 23 23:56 /dev/dsp0.0
crw-rw-rw-  1 root  wheel   30, 0x00010003 Aug 23 22:07 /dev/dsp0.1

crw-rw-rw-  1 root  wheel   30,   5 Aug 23 22:07 /dev/dspW0.0
crw-rw-rw-  1 root  wheel   30, 0x00010005 Aug 23 22:07 /dev/dspW0.1
crw-rw-rw-  1 root  wheel   30,  21 Aug 23 22:07 /dev/dspW1.0
crw-rw-rw-  1 root  wheel   30, 0x00010015 Aug 23 22:07 /dev/dspW1.1
crw-rw-rw-  1 root  wheel   30, 0x00020015 Aug 23 22:07 /dev/dspW1.2
crw-rw-rw-  1 root  wheel   30, 0x00030015 Aug 23 22:07 /dev/dspW1.3
crw-rw-rw-  1 root  wheel   30, 0x00040015 Aug 23 22:07 /dev/dspW1.4
crw-rw-rw-  1 root  wheel   30, 0x00050015 Aug 23 22:07 /dev/dspW1.5
crw-rw-rw-  1 root  wheel   30,  11 Aug 23 22:07 /dev/dspr0.0
crw-rw-rw-  1 root  wheel   30,  27 Aug 23 22:07 /dev/dspr1.0

And no /dev/audio:

newhope:mpg321 {566} ll /dev/audio*
crw-rw-rw-  1 root  wheel   30,   4 Aug 23 22:07 /dev/audio0.0
crw-rw-rw-  1 root  wheel   30, 0x00010004 Aug 23 22:07 /dev/audio0.1
crw-rw-rw-  1 root  wheel   30,  20 Aug 23 22:07 /dev/audio1.0
crw-rw-rw-  1 root  wheel   30, 0x00010014 Aug 23 22:07 /dev/audio1.1
crw-rw-rw-  1 root  wheel   30, 0x00020014 Aug 23 22:07 /dev/audio1.2
crw-rw-rw-  1 root  wheel   30, 0x00030014 Aug 23 22:07 /dev/audio1.3
crw-rw-rw-  1 root  wheel   30, 0x00040014 Aug 23 22:07 /dev/audio1.4
crw-rw-rw-  1 root  wheel   30, 0x00050014 Aug 23 22:07 /dev/audio1.5

So the system seems to recognize both of my sound cards,
but how can I use them and do I have to create /dev/dsp
and /dev/audio manually?

For example I don't have sound with mpg321. I've tried:

    mpg321 -v -a 0 file.mp3
and
    mpg321 -v -a 1 file.mp3

and see something is happening, but there's no sound to hear.

Mplayer plays from 1 sound card, but how do I select which
card to use and also the sound is not so good (interrupts).

Also in KDE in the settings dialog for "Sound system", should
I start aRts and set "Use custom sound device" to /dev/dsp0.1
(won't that be mono sound out of the 1st sound card)?

Thank you for any advices, I'm a bit confused how to set it up.
Alex
