I'm the (un?)lucky owner of an M-Audio Fast Track Pro USB audio
interface and I'm having some serious problems getting this device to
record audio reliably under Linux.
I've been using arecord and occasionally Audacity for all of my
testing. My problem is this: Recording a take works about 80% of the
time. In the remaining ~20% of cases, the captured audio is extremely
loud with severe digital distortion. Once this problem shows up, it
persists for any subsequent takes. The only way I've found to make
the problem go away, at least temporarily, is to power-cycle the Fast
Track Pro.
I considered the possibility that this particular device might be
defective, but it seems to work wonderfully under Windows.
I'm calling out to other Fast Track Pro users in the hope that someone
out there has encountered the same problem and better still, found a
solution.
Any suggestions at all would be greatly appreciated!

Hi.
Quite a shot into the dark, but: Is anyone here by chance into
eurorack modular and has tried the Expert Sleepers ES-8 USB Interface
with Linux yet? It claims to be class compliant, but you never know...

Hello,
I have set the scaling governor to 'performance' by doing:
echo -n performance
> /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
For all 4 CPUs.
After reboot, the scaling governor indeed shows:
% date
Sun Oct 22 08:53:49 EDT 2017
% cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
performance
performance
performance
performance
But then shortly thereafter:
% date
Sun Oct 22 08:54:06 EDT 2017
% cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
powersave
powersave
powersave
powersave
Which mechanism decides long after boot that the scaling governor
should be modified and how to tell it that 'powersave' is not what we
want ?
Cheers.
Hi
I have been using jackd to play music from my laptop -> server -> hifi.
It works well apart from I will get dropouts in the audio now and
then. I have been looking at the options for client and server and
trying all sorts of things to try to fix the dropouts, but I can't
seem to cure the problem.
My laptop is connected via cable rather than wifi.
NIC on laptop:
Ethernet controller: Intel Corporation 82579LM Gigabit Network
Connection (rev 04)
NIC on server:
Ethernet controller: Broadcom Corporation NetXtreme BCM5751 Gigabit
Ethernet PCI Express (rev 21)
Jackd command on laptop:
set_rlimits /usr/bin/jackd -dnetone -n60 -I0 -O0 -r44100
Jackd command on server:
set_rlimits /usr/bin/jackd -P 10 -p128 -t10000 -dalsa -dhw:DGX,1 -r48000 -p128 -n3
-P -I32
jack_netsource -H raven -r50000 -n1 -i2 -o2 -I0 -O0
I've been trying out different latency settings on server and client,
but they either don't make any difference, or jackd refuses to start.
Any ideas for getting rid of dropouts/xruns on the network?

Hi list,
I have been search the archives and the web a bit and it seems there is
no easy way to route html5 audio playback from firefox through jack on
Debian testing.
Is this still the case or has there been recent development that might
enable it? What would have to be done to make it work? This
functionality is the last piece in my puzzle to finally get rid of
flash.
thanks for pointers,
P

You know, 999 times out of a thousand, I do exactly that. Naturally, the
only time in, like, the last year that I forgot to do that, I got a
spanking *lol*
In fact, I was pretty well horrified when I saw the next digest. I
appreciate the recommendations, but it was a lapse of attention on my part,
not general cluelessness.

FWIW, I haven't used a FTP in Linux for some time, but when I did, occasionally I got the same thing: clean output, distorted input. I guessed that the endianness disagreed. But it was sporadic.
So you're not crazy. It really does happen and it's not a hardware problem with the box.
I don't have a solution, though.

I have for almost a decade now been using ffado and an Echo Audiofire12.
It is plugged into the firewire card and powered on, hadn't thought to mention...my bad.
Interesting point on the alsa driver for firewire. I did note on my other machine where this all works that alsa does see the AF12, as does jack.
I rarely look at alsa, so I have no idea how to tell if the fw alsa driver is loaded. At least some part of alsa it is there since if I select it as the driver with jack_control and start jack it finds the sound devices on the MOBO.
AS I said this behavior of UBS install is new to me, since it has always just found everything. Of course the only common things are the AF12 and UBS 16.04. The MOBO, fw card, etc. are new.
And the entirety of ffado-diag:
