Behringer Uphoria UMC204 usb audio capture only pops and clicks

Behringer Uphoria UMC204 usb audio capture only pops and clicks

[Andrew Reyes]

I have a usb Behringer Uphoria UMC204 and it seems to work fine at 44.1khz
full duplex but anything higher than that I get consistent pops and
clicks.  I notice it's on the capure side of things as when I have it in
playback only it's quiet. I have to say I'm testing this using JACK so this
is how I noticed it on the capture only side of things. I'm not sure
exactly whats needed to debug this issue. Any help would be appreciated.
Thanks in advance.

Could you send the output of 'lsusb -v', please?

Should I be posting somewhere else. If so can someone let me know where?

Please don't start a new thread every time you post but reply to an
existing thread. Given the traffic on this list, the conversation is not
easy to follow otherwise.

Regarding your issue - the descriptors look sane AFAICS. Please have a
look at /proc/asound/card/xxx/stream* (where xxx is the index of your
USB soundcard), and report the actual streaming frequency when playing
at rates higher than 44.1khz.

You can also monitor the values automatically, like so:

(while sleep 0.123; do grep 'Momentary freq' /proc/asound/xxx/stream0;
done) | uniq


Also, how to you play the audio? Try with aplay, and try to tweak the
values in the --buffer-size parameters.

How do I reply to an existing thread? I'm not clear on that. Sorry about
that. I was under the impression I had to reply by using the same subject
description.

Ok, so the actual frequency is close enough to the nominal one. Please
also do the tests wit aplay to see whether your issue can be recovered
by chosing larger buffer sizes. Do you see any messages in dmesg when
these 'clicks and pop' occur?

Also, please try this one:

  (while sleep 0.123; do grep 'Momentary freq' /proc/asound/xxx/stream0;
done) | uniq

Re: Behringer Uphoria UMC204 usb audio capture only pops and clicks

The while shell command shows consistent 96k when set at 96khz and dmesg
shows nothing where it pops and clicks.  How do I use aplay to adjust
buffer-size?

aplay -Dhw:xxx --buffer-size 2048 file.wav

(again, xxx is the index or short name of your audio card).

Which application do you normally use to play audio?

I'm using JACK right now for recording and gigging live and pulseaudio for
Youtube and movies.
Here is the pastebin link for the aplay command:

Bot should of course work, but as they're built on top of ALSA, it's
best to debug directly on the lower level. IOW: with aplay.

Ok, in this case, please use "plughw" instead of "hw".

Ok that worked. It plays fine at 44100 but when I try to set
`--period-size=48000` it still defaults to 44100.

I'm sorry I meant to `--rate=48000`.

Generate some sine wav files in various rates with something like
audacity and play them. FWIW, a 192k file can be found here:

  http://zonque.org/sine-192khz.wav (~22 MB)

Ok I will try that now.  I should let you know that I just tried the
arecord command for that same device at 48000 and it pops and clicks just
as in JACK.

Re: Behringer Uphoria UMC204 usb audio capture only pops and clicks

Ok I did playback on a 48khz song and no pops and clicks.  So it's just on
the capture side only.  What could cause that on the capture side of things?

I can just give you a few more ideas to debug this, but that includes more action from your side.

* First of all, try the same device on a different computer, and/or a different USB port, especially if you're using an XHCI (USB3) port.

* Try the device on Mac OS X, without installing a driver and see if you have the same problem here.

* Use usbmon and analyze the data stream when a pop occurs. Compare that with settings that don't produce pops. There's good documentation on usbmon in Documentation/usb/ in the Linux kernel.

Ok cool. I'll get right on that. I did try the first suggestion on four
different computers and different ports and it's the same issue but just to
be thorough I'll check again.

Daniel I got my hands on Windows 7 PC and installed the drivers from the

Daniel it turns out with a brand new UMC204 it still does it on my linux

Try that one on Windows as well. Uf it doesn't work there either, send tge hardqare back and get a different model. If the hardware has such severe bugs, there nothing the Linux driver can do to fix it up.

Behringer Uphoria UMC204 usb audio capture only pops and clicks

[Andrew Reyes]

I have a usb Behringer Uphoria UMC204 and it seems to work fine at 44.1khz
full duplex but anything higher than that I get consistent pops and
clicks.  I notice it's on the capure side of things as when I have it in
playback only it's quiet. I have to say I'm testing this using JACK so this
is how I noticed it on the capture only side of things. I'm not sure
exactly whats needed to debug this issue. Any help would be appreciated.
Thanks in advance.
