Dear all,
I know, this has been asked already in the forum.
But I could not find any solution. Maybe someone could help me.
I just bought an USB audio card and installed the drivers as described on the site http://dns323.kood.org/hardware:sound.
I really like the idea to just have one system running (and consuming power) and to control it via my tablet.
It seems to work as I can hear the sond that is played with mpg123 (via ssh on my receiver.
But when the song ends, mpg123 does not stop. Instead it blocks ssh and the drivers completely.
I have to reboot my DNS 323.
Currently I am using FW 1.09.
The drivers seem to be loaded correctly as dmesg gives:
usbaudio: device 2 audiocontrol interface 0 has 1 input and 1 output AudioStreaming interfaces

During installation I also did:
cd /dev
mknod -m 660 mixer c 14 0; chgrp audio mixer
mknod -m 660 mixer1 c 14 16; chgrp audio mixer1
mknod -m 660 dsp c 14 3; chgrp audio dsp
mknod -m 660 dsp1 c 14 19; chgrp audio dsp1
But when doing e.g. "chgrp audio mixer", I get the following error:
chgrp: unknown group name: audio
Is this a problem?
How should I create the group audio?
Is it maybe a problem that the drivers are built for FW 1.03 as mentioned on the site http://dns323.kood.org/hardware:sound?
Where to get drivers for newer FW?
Unfortunately I am not really familiar with Linux.
Thanks for any help!

Today I tried it again with a new "fresh" system and firmware 1.10B7.
Again I have the same situation.
The drivers are loaded successfully, I can hear music on my usb audio stick.
But when the music stops, the system hangs.
Only after a reboot, I can play music again.
What could be the problem?
How to compile the necessary modules (ko-file)?
I also tried to run alt-f, but the sound modules are not included (at least I could not find them).
Thanks for any help.
Best regards

After playing around a little bit more, I found out the following on http://buffalo.nas-central.org/index.ph … nd_card.3F
At least for my DNS-323 with firmware 1.10B7 I just need the following to hear music over my USB audio stick
insmod soundcore
insmod audio
a "lsmod" gives

audio 40512 1
soundcore 7620 2 audio
usblp 10976 0
sd_mod 14484 8
and "dmesg" gives

If I try to play some music by typing the following, it works. I can hear music.

Title: Live and let die Artist: Guns N' Roses
Comment: Album: Use your Illusion I

[3:02] Decoding of Live and let die.mp3 finished.
But still the same problem.
After 3:02 the process hangs!
Starting a new telnet session I can see the process via "ps":
2044 root mpg123 /mnt/HD_a2/Steiner/Musik/Music/Guns N' Roses/Use Your Illusion I/Live and let die.mp3
But I can't kill the process.
So all I can do is reboot the DNS-323 :-(
Unfortunately I found at the end of the above mentioned webpage the following hint:
Using OSS I could get sound playback (including mp3 decoding using mpd) but when the buffer was empty (press stop / file end / etc) it would hang the process and only a reboot would regain control. This was using a cheap "3D Sound" usb device with a JMTek chipset (ID 0c76:1605).
So it seems I have this chip.
Does anybody know how to check this?
It seems alsa is not running correctly as the "how-to" describes on http://dns323.kood.org/hardware:sound
Does anybody know how to get alsa running on DNS-323?
Thanks for any help.

Meanwhile I tried another USB audiostick, but it was even worser.
So at least with the Terratec Aureon Dual I have the described troubles and the music player hangs after stopping music playback.
With the Speed-Link Vigo USB Audio Card it was worser, sometimes no sound, but always the player hangs after stopping music playback.
It seems to be a difficult topic as no answer came although almost 300 people read the thread.
Currently I am out of any idea how to go on.
Unfortunately I have to stop my activities due to lack of knowledge and time and so I have to search for an alternative way.
Maybe http://dns323.kood.org/forum/viewtopic.php?id=4440 would be a good idea and worth to follow.
Thanks and best regards

I had the same problem with my ZyXEL NSA-220 (Same SoC, other kernel version). I found no other way to solve it then booting a custom kernel using reloaded.ko.
It seems that selecting the kernelmodule usb_audio.ko in .config also changes something in the kernel.

Sorry, but I am not familiar with Linux on this level.
I even can't compile a kernel as I am not able to install gcc (I tried, but I failed).
