Hi Markus,
maybe just a CPU hiccup? You can try to reduce CPU load by removing the
decimating rational resampler, and integrate the decimation into the Low
Pass (it does the same thing, with one filter less).
By the way, there might be a slight mistake in your flow graph, as it is:
After the first
Hi Marcus,
ok, here is the sketch:

There is no squelch in the data path. But thanks a lot for explaining
the effects of a squelch.
Maybe there is another reason for my observation, because I unplugged my
antenna from the rtlsd
Hi Marcus,
I have been reading from you more frequently on this list than you've
been reading from me :-)
I have my setup in my office computer, so I will send the setup to this
list tomorrow.
Thanks ahead!

Hi Markus,
nice to be hearing from you!
I'm making assumptions about your RX flow graph here:
osmocom source --> squelch of some sort --> FM demod/ AM demod of sorts
--> Audio sink
If the squelch is set to stop the flow of samples as long as there's not
enough signal, then downstream, the audio
Do you have a sqelch anywhere in your flow graph?

Hi,
playing around with my RTLSDR stick (RTL2832U / Rafael Micro R820T
tuner) I observed that whenever the reception (signal quality) is bad, I
am getting Audio Underruns and glitches in the accoustics.
How can that happen? I always thought the sample rate was constant? When
designing the sketch
