I have a jurassic ens1371 audio PCI card. It is used just as a monitor port leaving anything else to newer peripherals. This card has a joystick port. I found an old joystick so would like to try this out. There are even MIDI controllers around that can make use of it. Unfortunately, everything found by Google on how to set this up is very out- of-date. Some file or script somewhere, not where all these instructions say it should be, needs be around setting the joystick-enabled to true. I tried /etc/modprobe.d but that did not work. Anyone done this? Gameport is in /etc/modules and gets modprobed and lsmod shows it tied to the ens1371.

pulseaudio (again)

by Will Godfrey

In a moment of stupidity I managed to trash the install on one of my machines. There was no practical way to undo the damage (this is debian testing) so I did a fresh install from scratch - I must say the debian install discs have improved a lot! Anyway the first time I tried to do any audio work I got Xruns all over the place on stuff that had been rock-solid previously. However, a quick look at htop revealed that pulseaudio was running three threads right in the middle of the jack stuff. Deleting just the 'pulseaudio' server cured the problem, and nothing else seems to complain. The icing on the cake is that various programs that like to make annoying beeps and bongs are now quite silent :) -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Other crackles

by Fons Adriaensen

Hello all, The thread on 'crackles in audio' reminded me of a similar problem which upset me for some years now. I normally run Jack all the time, and for apps that don't support it there's an ~/.asoundrc like this: pcm.!default { type plug slave { pcm "jack" } } pcm.jack { type jack playback_ports { 0 zita-mu1:in_2.L 1 zita-mu1:in_2.R } capture_ports { 0 system:capture_1 1 system:capture_2 } } If you don't know what zita-mu1 is, see here: <http://kokkinizita.linuxaudio.org/linuxaudio/zita-mu1-doc/quickguide.html> The only use case for this is viewing youtube videos with either Chromium or Firefox, which will use ALSA's default device. This works ok but after some time I get 'crackles'. It sounds like a buffer wraparound. Repositioning or stopping/restarting the video usually solves the problem, but it will come back after some time. I see no reason why things shouldn't 'just work'. And I've been wondering: is this a long-standing problem with ALSA's Jack plugin, or are the browsers doing something wrong ? In either case, is there a solution (not involving PA or loop devices) ? Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)

Audio interface for newbies ?

by jonetsu＠teksavvy.com

If one would like tu use Linux as an audio workstation with say, Ardour to do the recording, all housed inside a midsize tower i5 or so computer, what would be the recommended audio interface ? The one that integrates to Linux 99% and works really well while providing a certain number of I/Os ? There must be one that satisfies serious home (or small studio) uses. I do not believe that all Linux audio users are clinging to their legacy, no-longer-sold M-Audio 1010 interfaces :) Cheers.

new Vintage Fuzz Master Plugin (LV2)

by Hermann Meyer

Yet a other one off the mini series from GUI-less LV2 plugs, This time, a analogue simulation of the Vintage Fuzz Master (Devi Ever) This one comes with a bass/bright switch and is a bit modified to produce less Volume then the original pedal. With "Intensity" down, it will blow up the low end, but by turn it up, it produce the well known and loved octave up artefacts. https://github.com/brummer10/GxVintageFuzzMaster.lv2 >All we wanna do is have some fuzz

[music] jam35 : electronic space folk

by jonetsu＠teksavvy.com

This piece is built around an acoustic guitar improvisation laid over a drum riff. Various sounds swishes around amongst phaser cymbals while a lead ethnic synth of future tribal times tells a story of not so quiet times floating over a loose and dirty bass. Enjoy. https://soundcloud.com/nominal6/jam35

Crackles in audio - how to troubleshoot ?

by jonetsu＠teksavvy.com

Hello, Suddenly the audio started crackling. I was listening to a youtube tutorial (firefox) and it started. Bitwig and Renoise were running but not playing anything. I looked at the log files (syslog, kern) nothing relevant. Card is 10101LT. jackd runs at about 10.3ms latency (last time I checked using jack_iodelay), so it run as: /usr/bin/jackd --sync -T -P95 -ndefault -dalsa -dhw:M1010LT -r44100 -p128 -n2 scaling_gouvernor all set to performance. Interrupt prio looks OK: PID CLS RTPRIO NI PRI %CPU STAT COMMAND 436 FF 90 - 130 1.6 S irq/18-snd_ice1 47 FF 50 - 90 0.0 S irq/9-acpi limits audio.conf is: @audio - rtprio 95 @audio - memlock unlimited Interrupts servicing for all 4 CPUs (i5) : 0: IR-IO-APIC-edge i8042 4: IR-IO-APIC-edge 8: IR-IO-APIC-edge rtc0 9: IR-IO-APIC-fasteoi acpi 12: IR-IO-APIC-edge i8042 18: IR-IO-APIC-fasteoi snd_ice1712 jackd and pulse processes: /usr/bin/pulseaudio --start --log-target=syslog [pulseaudio] <defunct> /usr/bin/jackd -T -ndefault --sync -T -P95 -ndefault -dalsa -dhw:M1010LT -r44100 -p128 -n2 The pa zombie was there way before the crackling started. Not sure if this is related. The pulseaudio jackd sink is active and can be seen in qjackctl. So it seems OK. But the audio is full of crackles. In firefox, as well as Bitwig and Renoise when now something is played. Of course, when the machine was started some audio was played in both Bitwig and Renoise and it was fine. Then I watched a youtube tutorial and bam, after maybe 15 minutes, all audio output is full of crackling. Since the log files shows nothing. How is troubleshooting information gathered ? There should be some SW system component that can be probed, somwthing that could be observed. - or is it that the 1010LT is going awry ? Can this happen at all ? Thanks for suggestions and comments ! Cheers.

Replacement for a 1010LT

by jonetsu＠teksavvy.com

Hi all, What's there on the market nowadays that works very well in Linux ? I use many in/out lines on the 1010LT. I use 5 line outs, 4 line ins, 2 XLR ins. I find it practical not having to re-connect things. Nice for recording. And also, not needing extra hardware to connect many lines to an interface limited in I/O is good. The replacement audio card should have a good number of I/o lines, as well as XLR inputs. Just got recently an ART MPA II pre-amp which I'm slowly exploring. So phantom power from an audio interface is not a criteria. Browsing the M-Audio site, the M-Track Eight rack mount USB unit might be something along those lines, although since I also have things connected to the 3 USB ports, I would tend to prefer one that does not use USB. Also, it sounds like it comes with controlling software that could be not available on Linux, or available with limited capabilities. Some for the Octane Preamp Technology M-Audio is boasting about that interface: not needed. I'd prefer putting money into the interface itself. The other offerings from M-Audio are those rather limited-looking interfaces with a big knob sitting on top. I do not know of any other serious audio interfaces out there - suggestions and comments are welcomed ! Cheers.
