getting sound working -- user id problems

by Rustom Mody

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 having issues... 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? Thanks Rusi

FREE GeneralMusic RealPianoExpander MIDI tone generator

by stephen.doonan＠gmail.com

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 shipping. 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 international shipping. 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 search. Best wishes, Stephen Doonan New Mexico US

FREE giveaway: M-Audio Delta 1010 Audio Interface

by stephen.doonan＠gmail.com

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.

Jack X-run

by Lucas Takejame

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.

Help with configuring a laptop for Linux Audio work

by Louigi Verona

Hey guys! Recently I've bought a Lenovo IdeaPad B590 laptop. As it is announced as an Ubuntu-certified laptop (here<http://www.ubuntu.com/certification/hardware/201208-11535/>), 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 well. 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 here<http://linux.autostatic.com/2013/12/29/resolved-jack-issues-on-notebook> . 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. Cheers! -- Louigi Verona http://www.louigiverona.ru/

no pastebin etc. please...

by Jörn Nettingsmeier

hi *! 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. best, jörn -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net

qjackctl bubbles

by Peter P.

Hi list, dear Rui, 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 qjackctl! best, Peter
