Hello,
I am having trouble with the usb driver for the M-Audio Duo usb
external sound card. I use kernel 2.4.21-2-686 on a Debian system.
alsa-driver-0.9.5
In order to do this I used Clemens Ladisch's midisport-firmware driver

OK, here is more data. The enclosed files are:
1) The "minimal playback program" described in the original message,
modified to clear the buffer, and do the "dump" of the parameters. The
buffer size is lengthened a bit (maybe this makes a difference??)
2) The output of 'strace' on the program, it

This is a nice coincidence, because I just installed Debian Sid
('unstable') on my home workstation.
I am also a convinced Debian user, and all the servers and workstations
I administrate are Debian Woody ('stable'). Now, recently, I have seen
myself forced to install more and more backported pac
That does the trick. Here's a patch against 0.9.5.
I don't know if this is related, but one thing I've been puzzling over
is that half the time after I plug in the audiophile I get static
instead of sound. I have to unload alsa and plug it in again. (As I
mentioned before, I always get stati
Hi all,
I am using the Terratec EWS88MT (VT1712 / Envy24 based) soundcard and would
like to route the digital mixer output to the consumer output (headphone
socket) using the "digital mixer to ac97" option in alsamixer. The signal
is routed correctly, but it is only a mono version of the stereo
Hi,
I am somewhat new to Linux low-level development. I have developed for
other UNIX systems before, and also for Windows NT and for JavaCard
compatible smartcards.
I have used (and enjoyed) Debian for a long time as a Linux user and for

Hi,
QAMix-0.0.4_pre03 is a QT based mixer for ALSA. The GUI is configurable
via XML. Default interfaces for standard AC 97 cards and Soundblaster Live
are provided. QAMix can be controlled via MIDI. Any number of MIDI events
can be bound to any mixer control.
It seems as if the code is now quite

I found that a better example for playback is
the 'pcm.c' file that you can find on the alsa site.
It contains many ways to deliver the data (a nice
sine) to your soundcard. Playing with the parameters
gives some insight (more than reading the overall poor
documentation imho :().
Anyway - I "tran

Yes. i.e. it will play a 44100 hz or whatever stream, but playback is
too fast.

Again, access is your problem. You requested read/write access. You have
to request mmap interleaved one (SND_PCM_ACCESS_MMAP_INTERLEAVED).

I did some investigation to find out why the sample rate can't be set to
anything but 48khz (or rather, remains 48khz even if it is set to
something else) on the Audiophile.
In init_usb_sample_rate(),
if (fmt->attributes & EP_CS_ATTR_SAMPLE_RATE)
is never true, so the sample rate is not
