Yeah this is probably not exactly a linux audio problem
Just thought someone here may have a clue...
I have a couple of linuxes on my box:
/dev/sda6 (LABEL=DebOld) is 32 bit debian
/dev/sda7 (LABEL=Deb64) is a recently installed 64 bit debian
Both these work ok. Both use xfce. Now I want to share the home and I am
On DebOld home is separately mounted from /dev/sda3
On Deb64 home is part of the root fs and I want to move to using the old
separately mounted home where all my stuff is
The problem is that the numerical id of the (my) username is different in
the two systems. In DebOld the id is 1001 in Deb64 it is 1000.
So I did:
In new (Deb64) change 1000 to 1001 in /etc/passwd and /etc/group against my
username. Knock off the password in /etc/shadow and regenerate.
To some extent this has worked. However now I am beginning to see problems
suggesting this was not such a neat hack!
So parole - the xfce media player - is refusing to play sound files from
the old (and renamed) home but is playing it from the new.
I am guessing this is a user perms and not really a parole issue since
parole plays ok if started as root
So I have basically one specific and one general question:
Specific: Any ideas about how to make parole (gstreamer) work?
General: There may be more such issues in other (sub)systems/apps.
Whats the general way to solve it?
I have an older GeneralMusic RealPiano Expander rack-mount (1 rack space
high, half-rack space wide) MIDI-triggered tone generator that rarely
gets used now that I have several other MIDI tone generators I prefer.
So I'm willing to give this RealPiano MIDI module away for the cost of
The front LCD display of this GeneralMusic RealPiano Expander module no
longer works well, but if one can learn to use the unit almost "blind,"
using the front panel buttons instead of the LCD screen, this unit
produces some very fine sounds from the digital samples and acoustic
modeling, of piano, Fender Rhodes, Wurlitzer electric piano and several
other types of keyboard or percussive (like vibraphone) sound.
United States only, unless I am persuaded to try to arrange
If you are interested in the unit, please write to me directly (don't
pollute the linux-audio-user email list), and please explain why you
would like this MIDI tone generator, in case more than one person is
interested and I need to make a decision about which person to give it to.
I'm sure that there is information on the Internet about the
GeneralMusic Real Piano Expander for anyone interested enough to do a

M-Audio Delta 1010 FREE for shipping charge, United States
Hello all-- I have an older M-Audio Delta 1010 audio/MIDI interface
(rack-mountable breakout box and PCI card combo) that I've used for
years, but I recently upgraded to a new computer and the Delta 1010 PCI
card uses an older PCI specification.
So I bought a new audio/MIDI interface and am willing to give away my
trusty older Delta 1010 for free to someone in the United States who
would like it and uses a computer with an older motherboard designed for
an older PCI standard.
Manual, cords and everything included.
Hey guys, I having a strange issue with jack, when I start Qjackctl with
256 frames/period it works fine, but when i change to 128, it starts
popping Xruns with nothing connected or instantiated at all! The most
strange part is that I don't even remember installing or changing anything
these days and this started to happening out of nothing, it used to work
fine with any frames/period. Here are some information:

It's been a while, but finally I am getting back on track with the
"droning" project. Here is a new batch for you, tunes 233-240.
Get 'em here: http://www.louigiverona.ru/?page=projects&s=music&t=droning
droning233 - calm waves of sound, pretty relaxing tune
droning234 - some pads and bell-like sounds
droning235 - a curious experiment with choirs and even a little structure
droning236 - nice classical drone, calm, thoughtful and very much in style
of the first hundred
droning237 - dark tune, rich in timbre, soundtrackish, a little structure
droning238 - some arpeggiation action
droning239 - loop shifting, I believe a successful take on it
droning240 - epic sounding tune, mysterious
Recently I've bought a Lenovo IdeaPad B590 laptop. As it is announced as an
I did not think twice if buying it and thought that there would hardly be
an audio problem - I've used Lenovo laptops before and audio worked very
However, I was disappointed. Not only had I to use wired Internet, as wi-fi
does not work without installation of proprietary drivers, not only had I
to install a later kernel, as video card was freezing the system, but Linux
Audio does not work well at all.
I am using Xubuntu 12.04 with kernel 3.8 now.
Here's what has already been done.
1. All real-time priorities and audio group and such standard stuff set up,
checked and rechecked by myself and other people at LAC.
2. Autostatic was kind enough to help me turn off bluetooth and webcam,
which did seem to help a little bit. His tutorial on this is
However, my problems persist.
There are two distinct problems.
*Problem 1. Xruns.*
Even if nothing is done on the computer and/or with audio, xruns are
generated. For instance, since I started writing this letter, JACK was on
and right now I have an indicator of xruns in qjackctl which says: 7(13).
Note, no audio programs are open at all. If I do nothing, just turn on JACK
and leave laptop running, xruns are also generated.
*Problem 2. USB interruptions.*
This problem occurs when I am using USB soundcard or USB headset. I get
regular audible interruptions of audio signal. It has no bearing on xruns
and occurs even outside of JACK, just when I am listening to Audacious, for
example. I tried switching from PulseAudio to ALSA, same result. I though
do not remember checking this with YouTube videos, for instance, and right
now have no usb devices at hand to check.
I would be very grateful for all the suggestions as it would be a pity if
this laptop would eventually turn out to be not suitable for audio work.
But I would rather find that out sooner than later, while I can still sell
it and perhaps buy another model.
i'd like to suggest that people refrain from using pastebin and other
ephemeral upload mechanisms for mailing list discussions, because that
will make the list archives next to useless. imagine the frustration of
a user who googled a problem and was getting her/his hopes up, only to
find that all relevant information was on pastebin and has since gone to
the bit bucket.
i'm a big fan of pastebin for IRC and the like, but it kinda defeats the
purpose of mailing lists.

I am a happy qjackctl user. Nevertheless after more than five years I
must say that I have already learnt that jackd will continue to run if
I close the qjackctl main window and leave it there as system tray.
The same goes for the bubbles that announce a problem, or the need to
restart after doing changes.
Is there any chance this might be addressed in a future update,
like as a configurable option? Could one at least try to comment it
out in the source code and recompile?
Thanks to the list for support and to Rui for writing and maintaining
