Error from GNURadio block

[Astromis]

Hello.

I use the XTRX in my projects and recently I've found an error that causes when I'm trying using it in GNURadio with Audio Sink block.

In the end of post I've attached a log from GNURadio terminal as well as GNURadio simple FM receiver graph where problem causes.

I use latest program modules including driver, libxtrxll, libxtrx and so on. XTRX is connected through miniPCIe. OS Ubuntu 16.06. osmocom Source is built from xrtx repo as well.

Try placing 'xtrx' in the device arguments of the osmocom Source block. This will bypass Soapy and use the actual xtrx drivers. See if that helps.

Hi Astromis, just wanted to see if you have been able to test this? If it worked that would be good to know so they can close this issue. Thanks!

Hello @Astromis I am having the same error but I'm using USB 3. I would like to know if you can fix it. Thank you.

@Brayan1710 hi.

Unfortunately I can't help you now. You see, It was 2 years ago when I worked with xtrx but now I'm working in a different field. Sorry.
