I thought that I remembered that the Midiman Audiophile 2496 had been working with spdif for a while for me at least, though I have the dat on the Delta 1010 in the music room now.
I know that there was a lot of ups and downs with the drivers and spdif at first.
I did have to cook up my own .asoundrc for it, but that's kind of expected with a mutichannel chip being used on a simple card.

Hi all,
This might seem like a silly question, but I'm having an
unexpectedly hard time putting together something I consider
to be quite simple in essence.
The intent: play music from PC (eg .ogg/.mp3 etc) via S/PDIF to
an external DAC, and thence to sound system.
The problem: finding a soundcard supported by Linux and which
offers the option of unadulterated digital output. Ie. I want the
soundcard to simply stream the bits at 44.1Khz (or 48) and not
shag around with it in any way.
My current setup is a compromise. I have onboard sound with
a VIA8233 (Avance AC'97) 6ch chipset, and am using Windows
XP with this, since the latest ALSA driver doesn't produce any
sound on the S/PDIF output (although the optical port lights up).
Trouble is, I don't trust the Windows driver, since the control
panel for it allows me to select DSP environments and use a
graphic equaliser. With the environment set to "none" and the
equaliser off is it providing a "pure" bitstream un-molested in any
way? Who knows.
So, the question to you is simply: do you know of any soundcards
which would fit the bill - ie. with a fully working Linux driver, and
known to be configured to produce "pure" digital out.
Cheers,
Paul.

Lubarsky's Law of Cybernetic Entomology:
There's always one more bug.
Good morning,
I read (somewhere) that it is possible to make a directly useable Hard
Disk 'Image File' from an Audio-CD.
I am familiar with mkisofs for sets of data files and mounting the
iso-9660 images as loop(ed) devices to access the files within the
resulting image file.
Also, I know that cdrdao builds a .bin temp file when you make a copy
...
Are these files interchangeable? How would one mount an Audio 'image
file' to play it, since you usually do not mount Audio CD's - players
like xmms just use the raw device (right?)
Any hints or pointers (urls) would be appreciated.
aloha,
dave
Hi,
ams-1.5.5 is available from http://www.suse.de/~mana/kalsatools.html.
It fixes a serious bug in synth.cpp which causes the machine to freeze
when ams is started as root.
Some example patches for the bode frequencer LADSPA plugin included in
the new 0.3.3 version of Steve's plugin set have been added as well.
Have fun !
Matthias

Hello list!
(I have searched for an answer to this question in
google and some other lists but didn't find something
helpful... sorry if this has been asked before)
i want to have realtime-encoding of my soundcard
line-in with sox and lame (or something similar - i
need command line tools). Now i use
rec -t wav -r 44100 - | lame -m m -a -b 64 -
(i need 44.1 khz/64 kbit). But all 5 or 7 hours sox
crashes; there's an older thread on the sox mailing
list:
http://sourceforge.net/mailarchive/forum.php?thread_id=1083489&forum_id=3958
which says that this is due to a counter in the wav
header which overflows and that you should use .raw
instead of .wav. But whatever i use doesn't sound
right:
sox -t ossdsp -w -s /dev/dsp -t raw -r 44100 -c 2 - |
lame -r -m j -b 64 -x -s 44.1
--resample 44.1 -
It sounds dump:
http://www.kochenmachtspass.de/test3-ms.mp3
I have tried many other options like -c 1 (leads to
noise) but i cannot find a solution... Maybe someone
of you knows a solution?
Thanks

Does anyone have any recommendations for cheap SMP motherboards?
Something that can handle a couple 667 PIIIs would be ideal, but if the
total price including CPUs is <$300, I'll consider it.
My motherboard seems to not work with SMP anymore (freezing, restarting).
I'm pretty sure it isn't a kernel thing because I've tried every version
between 2.4.17 and 2.4.20 and they all act the same. It used to be rock
solid at 2.4.18.
Alternatively, I'd like the name of a good vendor of motherboards.

Thanks Paul.
I'm still struggling with getting this new card going. Fernanado and I
are working through the issues one at a time by doing a Planet RPM for
the newest version alsa and have applied the one line patch that you
pointed me at the other day. However, I'm still not running.
1) Fernando applied the one line patch applied:
--- hdsp.c-orig 2002-12-03 19:28:40.000000000 +0000
+++ hdsp.c 2002-12-03 19:28:06.000000000 +0000
@@ -2966,6 +2966,7 @@
switch (rev & 0xff) {
case 0xa:
+ case 0x64:
/* hdsp_initialize_firmware() will reset this */
hdsp->card_name = "RME Hammerfall DSP";
break;
2) Alsaconf works, sort of. modules.conf gets built, but my machine will
not reboot after running it. Don't know why.
3) When I boot I see the following message in /var/log/messages
Dec 9 12:39:40 Godzilla kernel: Hammerfall memory allocator: buffers

4) lspci -v shows the card is there:

I'm completely puzzled. What are we doing wrong?
Thanks,

sorry for the crosspost, but i'm not getting any response from
alsa-user list and I know these devices have been discussed
here before. I've searched the archives thoroughly, but
found no report of anyone succeeding in using an oxygen
via usb with recent version of alsa. Is that still the
case?

I picked up an Oxygen today, and I seem to get as far as
getting the firmware loaded (via midisport_firmware)
and loading the snd-usb-audio module,
but I don't seem to be able to actually use it.
I have kernel 2.4.19, with the latest hotplug and fxload
sources from the hotplug sourceforge page (not from cvs).
When I start alsa, the snd-usb-audio module starts:
$ sudo /etc/init.d/alsasound restart
Shutting down sound driver: done
Starting sound driver: snd-ice1712 done
Starting sound driver: snd-usb-audio done
Starting sound driver: snd-virmidi done
Starting sound driver: dummy done
No state is present for card virmidi
When I plug in the oxygen I get this in /var/log/messages:
Dec 8 00:50:27 kermit kernel: hub.c: USB new device connect on bus1/1, assigned device number 5
Dec 8 00:50:28 kermit kernel: usb.c: USB device 5 (vend/prod 0x763/0x1014) is not claimed by any active driver.

I expect the oxygen to show up as snd-card-1 because that's what's in
my modules.conf:
# begin of alsa section of modules.conf
# for alsa native support
alias char-major-116 snd
alias snd-card-0 snd-ice1712
alias snd-card-1 snd-usb-audio

alias snd-card-3 dummy

alias sound-slot-2 snd-card-2
alias sound-slot-3 snd-card-3

alias sound-service-2-8 snd-seq-oss
alias sound-service-3-0 snd-mixer-oss

alias sound-service-3-12 snd-pcm-oss
# Here are specific module options for ALSA.

... but here's what I have:
$ cat /proc/asound/cards

So where's the oxygen????
What am I missing?
