Dear list,
the following problem is giving me headache since a very long time:
My RME Multiface connected via the ExpressCard to my Lenovo X201s
running Debian/GNU testing is 20% of the time detected as Digiface when
inserting the card into the computer. Dmesg tells me that
Hammerfall-DSP: Digiface found
I have to eject the card multiple times and power cycle the Multiface
until it is eventually randomly detected as the multiface it is.
Does anyone have any idea why this could happen? Does anyone have
similar experiences?
thank you so much!
Peter
Some folks are still contributing by writing RT patches for current
kernel version. Several people who aren't able to contribute by
programming are willing to help by testing. So far, so good. How can we
provide a useful bug report, when the distros we're using comenmwith
systemd? IOW journalctl rules.
I send requests to archaudio-discuss(a)archaudio.org and to
linux-rt-users(a)vger.kernel.org , but journalctl is an issue.
For more than a decade I'm using Linux only, but I'm unable to find a
way to get useful journalctl output.
Any ideas?
I apologize in advance for what seems like a trivial and often asked
question. But I can't seem to figure out even the tools to diagnose my
problem. I've been reading web pages and alsa and jackd documentation for
two weeks, with no luck.
I'm trying to configure my ubuntu 14.04 system to use my Akai EWI USB midi
controller. I am trying to use Ted's Linux MIDI Guide
<http://tedfelix.com/linux/linux-midi.html> to configure things. But before
I get midi working I need to test that jackd can route audio to alsa, and I
can't get audio ouput from jackd.
I have verified that alsa works with pulseaudio, when pa is running. I
disabled pa and then made sure that pa did not autospawn (autospawn = no in
/etc/pulseaudio/client.conf.)
I also verified that my hardware device is hw:0. It's the only HW device in
my machine. The EWI is not currently plugged in, and it's a MIDI device
anyway.
When I run qjackctl and start the server I get this:
19:04:28.770 D-BUS: JACK server was started (org.jackaudio.service aka
jackdbus).

I have played this .wav file before with aplay, so I know it plays, but no

qjackctl tells me this when I run jack.play:

I know it's some simple configuration error I have made. I have no
.asoundrc nor an
/etc/asound.conf file, so I have the default configuration. I also have
the most common
kind of sound card in the world, so it can't be that hard to configure it.
Can anybody give me a clue? Thanks.
P.S.
FWIW, alsa is working fine, so I don't think that's the problem. But
catting /proc/asound/cards gives me:
Code:
poppa@ossian:~/.config$ cat /proc/asound/cards
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xfdff4000 irq 16
Also, alsamixer tells me the levels are fine and not muted.
P.P.S. The EWI works with alsa and fluidsynth alone, but there seems to be
a noticable latency between fingering notes and hearing the notes. I'm
hoping jack will fix some or all of that.
I realize this isn't strictly a *Linux* audio question, but my question is actually platform-independent. I've recently realized that if I want to keep doing my vinyl to AIFF project on my new MacBook Air (running Yosemite), that Audacity doesn't officially support Yosemite.
Does anyone else use both? Or (for whatever reason) has anyone else had reason to have to migrate from Audacity to SoX?
(I admit one issue I have yet to even explore before installing SoX, is whether I can even use the headphone jack for analog input, or will I have to get an analog to USB converter?)
Thanks in advance, if anyone has thoughts.

Hi all,
i wonder if I can redirect audio from my android mobile phone to a jack
server (preferably) or pulse audio server (not so preferably) through wifi,
in much the same way this can be done through bluetooth.
So I already have a jack server running and the easiest would seem to have
jack running on my android and acting as a jack client, to send audio
channels to a jackd server that is connected with m home audio system.
I am willing to consider any preposition that involved using wifi for the
audio routing, rather than bluetooth.
Thanks!

Video cameras record at 48k rate, so someone will need to rate convert.
Either the camera audio will need to be converted to 44.1k or your audio
will need to be converted to 48k.
Which you choose probably does not matter, but everyone involved needs to
know and agree on the chosen project sample rate.
If the final output will be a video then converting every thing to 48k is
probably the easiest choice. If the final output will be a CD (or audio
only files) then probably 44.1k is the easiest choice. If you will have
both a video and audio only files, my choice would be working in 48k and
then sample rate convert the final mix to 44.1k for CD.

I have been trying to strategize cutting the USB cord (right now, one USB, one Firewire...) for my portable synth on and off for a long time; I really don't like wearing out USB ports and cables !!!! Was just perusing some of the AoIP conversation and thinking...and then a thought was given, did a search, and found:
https://www.hifiberry.com/
So, at least in theory, for about $160 or so, I could get one of those and an RPi 2.0 starter kit, run netjack and qmidinet, and have a 96kHz wifi audio interface with MIDI...? Anyone see an obvious catch?
