I'm on a Raspberry Pi 3B, using HDMI sound fed to a Dell monitor about 10 years old. No internal speaker in it but I use an analog out jack it has and drive a pair of amplified computer speakers. It's getting worse lately. If I unplug the analog input to the powered speakers it goes away. If I turn down HDMI sound in AlsaMixer it goes away. I can make a recording in Audacity of tone, silence, tone, silence, then play it and I near the frying on top of all like it's mixed in. I have no other (like USB) sound card plugged in. Where can it be coming from? _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
