hi Aidan,
guess you're using Primo Em272 mics? Try to move things, cables etc., but there's a chance that iqaudio zero doesn't work well with Primo Em272 mics. I've tried many configs for many hours, also voodoo (aka expensive audio cables and others). Sometimes it helps ;) Primo EM172 are working better, though Primomic told me that there's virtually no difference. But there is. My advice: use PUI AOM5024 microphones with Pi/Iqaudio.
bests, Udo

Hi Grant,
I see the following error in journalctl: "[locusonus@sherkin-streambox ~]$ journalctl | grep errorAug 22 22:07:42 sherkin-streambox alsactl[227]: alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2Aug 22 22:07:54 sherkin-streambox audio.sh[317]: alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:1 use case configuration -2 "
The install is a rpi zero, iquadio soundcard, over a huawei 3372 4g dongle. The noise is intermittent, and is much louder at night. At this point, I'm very much out of ideas as to how to handle this, or whether anything can be done. I suspect that there is EMI from the dongle. Annoyingly, I had the set up running for weeks in my backgarden with no issues. The streambox is installed on an island, so maybe the 4g signal is weaker there. Maybe the iqAudio + rPi isn't such a good combination if it results in such noise in the field? Aidan On Friday, 20 August 2021, 12:02:12 GMT+1, Grant Smith grant@soundtent.org wrote:
Hi Aidan Thanks very much for the new streaming project and letting us know. Listening in now I hear a lot of electronic noise, as you say. Can you give more details on the installation / streambox, and I'm sure we can troubleshoot bwgrant

Stream is here: http://locus.creacast.com:9001/sherkin_north_shore.mp3%C2%A0There is some quiet digital noise in the background. the streambox is mounted distant from the mics. I have SSH access. is there anything I can tweak remotely to address this noise?
Thanks!
