I've been trying to get mplayer to work with my delta44. I have
a working plug pcm type:
pcm.dplug {
type plug
slave.pcm ice1712
}
and
$ mplayer -ao alsa9:dplug foo.avi
will play audio, but no more than a few frames of video. If I look
at the verbose output I see;
alsa-init: requested format: 48000 Hz, 2 channels, Signed 16-bit (Little-Endian)
alsa-init: compiled for ALSA-0.9.4
alsa-init: soundcard set to dplug
alsa-init: pcm opend in block-mode
alsa-init: chunksize set to 1024
alsa-init: current val=7, fragcount=7
alsa-init: unable to set periods: Invalid argument
alsa-init: got buffersize=26212
The number of periods the driver requests is 7 which the code
obtains by calling snd_pcm_hw_params_get_periods_max(). So
my question is, what should this value be for a plug, should it
be the same as the underlying slave. Is the ice1712 not reporting
the correct maximum? The maximum jackd will start with is 5
periods so there seems to be something wrong here.

Hi,
I have a MIDI card (Yamaha DB50XG) that I use as a performer for my old
Ensoniq controller. It works fine. However, it seems that the Ensoniq
keyboard sends the velocity information at only half what it should be
-- if I pound on the keyboard, the volume is increased from normal
playing, but still rather quiet. If I play a midi file through tse3play
or something similar, the volume is full.
To get around this problem, I have two sysex files; I cat
volume_high.syx > /dev/midi when I want to use the keyboard, and cat
volume_low.syx > /dev/midi when I want to play midi files. The sysex's
each set the midi master volume to a level which is comfortable to use
with either.
However, this feels like a kludge. In addition, sometimes annoying
things happen like after I've been playing the keyboard at its
comfortable volume, I visit a web page with a MIDI on it, and it plays
at 250% volume and blasts my ear out. Or I play a game like DOOM which
has hardware MIDI support and have to lunge for the volume on my mixer
to keep from disturbing the neighbours. :)
The keyboard is a Ensoniq SDP-1 from 1986 or so. I tried the volume
setting on the keyboard in the hopes that it would modify the volume of
the notes sent to the midi card, but it seems to have no effect. (Is it
broken possibly?)
I was thinking about hacking the mpu401 driver so that when midi data is
received externally, it rewrites the velocity somehow before it reaches
the midi device. Or if that isnt possible, when a file is played to
/dev/midi, after the file sets master volume, reset it to a lower value.
Thoughts? Suggestions? This has been annoying me for a while now. :)
Thanks,

at the risk of degrading what I'm appreciating - I just wanted to send a
note thanking y'all for the great discussions and high signal-to-noise
ratio of this group. I've been lurking for three months, waiting till I
have the finances to buy equipment to try all this stuff - and sitting on
this list has been highly educational. the recent mastering conversation
is really diggable. thanks!

Hi,
How do I set the ouput line level of my delta 66 to -10dbv? Under
windows this can be done using the delta control panel but I can't see
any option for this in envy24control nor alsamixer.
thanks

I'm having trouble getting my audio hardware to work under linux. I'm
not sure if this is the correct place to ask a qustion like this
though... I'm getting noise on the audio input with a faint shadow of
what I'm trying to record. I'm trying to get one sound card working
first and hope to add one or two more.

For those list members who are going to the postponed LinuxUser &
Developer Expo next week in Birmingham (that's England, not Alabama)
is there interest in rescheduling the informal linux-audio-users
meeting I originally proposed?
I'm going to be there all three days, but I'd prefer to meet up on the
Thursday, say 12.30pm for lunch? Meet at the Rosegarden stand?
Hopefully it will have calmed down a bit by then and I'll be able to
get away from our own stand...
Cheers

Hi All:
I'm wondering if Dave Phillip's book 'Linux Music and Sound' is still a good
buy. Given that it was published 3 years ago, would much of the material now be
out of date?
TIA

Hello,
as both the participants of the 1st LAD conference and people at ZKM
enjoyed the meeting, Frank and I asked for the possibility to hold a
second meeting at ZKM next year.
The answer was positive and therefore we can announce that the 2nd LAD
conference is planned to take place April 29th - May 2nd 2004 at ZKM Karlsruhe.
the option to have more room. In addition to the rooms we had for the last
conference, we now have the option to also use a hall which is about double
the size of the lecture hall we used for the last meeting. This hall is even
more attractive since it is the recording studio of ZKM and can also serve as
a concert hall. This time there is also the option to invite artists who
actually do music with Linux software.
Early registrations (email either me or Frank Neumann <Frank.Neumann_AT_st.com>)
would help us to estimate the approximate scale of the event which can be
even larger than last time. If you can do a talk or presentation please let
us know the subject and estimated time you need for this. Depending on the
number of talks we can decide whether we will have two parallel sessions.
If the program of the event is fixed earlier than last time, this will
help to advertise it in journals and among relevant companies. It might
also help to find possible sponsors.
Updates on this will follow from time to time.
Matthias

The DSP24 works fine in Linux. There are a number of ST Audio products built on it. I have the DSP2000 C-Port and it works fine. M-Audio has a card based on the same chipset. I think it's the Audiophile 2496.

Audigy2 has faily decent all around linux support with Alsa, although I don't think you'll get at 24bit x 192khz i/o. It'll basically act as a Live! w/ really nice DACs :P
