Troubleshooting FAQ

This is a list of commonly occuring problems and questions, in no specific order.

No audio on specific clients, receiver starts to behave odd as soon as specific clients connects

Please check which version of csdr you installed. One of the most common problems is the missing deemphasis_nfm_ff filter for 12kHz audio, which comes into play if your client runs 48kHz audio (or other multiples of 12kHz, other reported cases were using 192kHz).

Please install my modified version of csdr to get rid of the error.

My OpenWebRX installation is missing some / all of the digital demodulation buttons

I set up my sdr source in the config, but it's not in the list / OpenWebRX doesn't list it as an "Available SDR"

There's probably some dependency missing. Please append /features to your receiver URL to get the feature report. Check if all the requirements for the sdr / demodulator in question are fulfilled.

My OpenWebRX works fine at first, but stops working when I disconnect and connect again.

This is something that has occured to me when using SDRplay devices, and they seem to be especially prone to this error when connected to a Raspberry Pi. The most probable cause for this is insufficient power supplied to the SDR, so the immediate recommendation is to use a different powersupply and / or a powered USB hub to fix this.

If the error remains, you can use the "always-on": True option on your sdr device to keep it running continuously. This, however, is just a workaround to avoid the error.
