I'm happy to announce the release of LiSP (Linux Show Player)!
"LiSP (Linux Show Player)" is a sound player specifically designed for
stage productions.
The goal of the project is to provide a stable and complete playback
software for musical plays, theatre shows and similar.
Features:
- Button matrix user interface, suited for touchscreens;
- Multiple tracks playback;
- Sound FX: gain, equalization, pitch shift, speed control and
compression applied in real time on each track
- Peak and ReplayGainnormalization
- Remote control over IP of slave/backup PC;
"LiSP (Linux Show Player)" is developed in Python and based on GStreamer
and PyQt.
"LiSP (Linux Show Player)" is available at:
http://code.google.com/p/linux-show-player/
Please report bugs using the issue tracker:
http://code.google.com/p/linux-show-player/issues/list
If you're a developer and want to contribute to "LiSP (Linux Show Player)", join the project.
Thanks.
P.s.
Probably I'll create a (google) group for developers and one for requests and suggestions from users.

That's great, "keep it simple" i should say...that's why i think it's
brilliant!

yeah, that's what happened to me and i still don't know why.
I'll try to increase the rtprio as well, good tip, thanks!

"Unbinding" the device to the controller it's not a good idea i
suppose,the PI shares both usb ports with same controller...

Maybe there's no need to install Ubuntu.
I found out that there are 2 apps: "Connectbot" and "X server" in the
market that that may do the job with android.
Connectbot doesn't provide the "-X" option so we should set up the
DISPLAY variable accordingly with the ip-port on the X server app.
Maybe i'm just wasting my time but i will give it a try...

"Happiness only real when shared"
C. J. McCandless
Hi folks,
The question earlier today about a stage worthy multi-track backing
track solution made me think of "Band-In-A-Box" a windows tool for
creating style bassed tracks. I also have an OLD!!! Roland arranger
keyboard which does something similar.
Is there an equivalent program for Linux which has banks of styles,
and you input chord sequences to be played by the "band?"
Thanks!
Rusty
Since two weeks I have a problem with my soundcard DSP2000 C-Port.(Hoontech)
When I start the computer the soundcard is not recognized by the system.
Sometimes it works when I restart the computer. But today I try to reboot
the machine four times and the card is still not recognized. I haven't hat
those problems before. The DSP2000has worked without problems for the last
two years.
I'm on ubuntu 12.04 kernel 3.8.0-14-lowlatency with KX Studio.
The power LED is on, but the other four LEDs for the channels are out.
I have try to start the driver in terminal:
sudo modprobe snd_ice1712
but nothing happens.
Any ideas?
thanks for help

Hi, although sidetracked by life for a while, I finally got around to
rebuilding my linux audio box.
It's a stock fedora 18:

3 [NVidia ]: HDA-Intel - HDA NVidia

I've shuffled the cards around the slots to no avail (only have 2 PCI
slots).
Could it be because they share the same bus (05) that somehow they don't
work together? Also, regardless of which slot the physical cards are
inserted into, only the delta 1010 is ever exposed by ALSA. To be sure,
I also confirmed that the 2496 does indeed work by inserting it into a
different test box.
Any insight would be appreciated.

Has anyone been able to email Jeremy Jongepier recently?
I've tried to contact him via my nomal address and me sourceforge one (don't
often use that). Both of these get rejected by a spam trap :(

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
As well as ogg and mp3 download links my site has a minimal in-line player.
Seeing as almost all browsers have their own embedded player these days I'm
thinking of removing mine. This will not only get rid of flash, but also the
javascript that supports it (and nothing else).
What do people think?

Hello,
We use Echo Layla 3G on HP Z400 workstations with Debian Squeeze (alsa
1.0.23) for two years.
Sometimes we get annoying timeout errors (wait_handshake(): Timeout waiting
for DSP). These errors mostly occur when the computer had been idle more
than one or two days.
Very very rarely we had timeout error while the computer was playing.
1. Computer's sleep mode is disabled from Gnome's power management.
2. Errors mostly occur while it had been idle for a along time. However, we
couldn't predict the exact time. In other words, we can't say that the
errors occur after 24 hour or 36 hour idle time.
3. Besides Echo Layla 3G, we have another soundcard. After the time out
error, although Layla doesn't work, there aren't any problems for the other
soundcard.
4. There aren't any information about the error, just,"wait_handshake():
Timeout waiting for DSP" lines.
5. We tried increasing timeout value for the echo3g driver. But nothing
changed.
What can we do? The error message (wait_handshake(): Timeout waiting for
DSP) is very limited. How can we find the real cause?
thanks

Not really any ideas... except I think the dsp2000 has a unit selection
switch on it that has to be set as the first unit (not sure if that is
unit 0 or unit 1) with dip switches. Maybe check that hasn't be moved by
accident.

I've just purchased an inexpensive USB cassette player in order to
archive/preserve some audio cassette recordings of some interviews I did
years ago, and I've run into a slight issue with the detection of the
device.
The device identifies as a JMTek USB Audio Device (Vendor 0c76, Device
160a). I'm using openSUSE 12.2.
When I plug the device in and connect to it with Audacity, and I only get
a mono channel (rather than a stereo setup). Looking at the output of
"lsusb -v", I see that the input terminal is identified as a microphone
with one channel. (Output of lsusb -v is at the end of this post)
If I start a Windows XP VM in Virtualbox and connect the device to that,
it is recognized (in Windows) as a stereo device, and I can record left
and right channels, so the hardware should be recognized as having stereo
channels via USB. There are no special drivers installed for the Windows
VM (it was just "plug and play").
I'd much rather not have to boot up a Windows VM in order to record audio
from this device. I also would prefer to not use line-in, as I almost
always have ended up with a 60 cycle hum recording that way, and I don't
get that if I record over the USB connection (the USB connection also
powers the device).
snd_usb_audio is automatically loading when I plug the device in.
Are there any tricks that I might apply to getting this device recognized
properly or to diagnose why it's being identified as a mono device?
Thanks,
Jim
