I'm hoping for a software solution, though. If the above sound chain is correct, then you don't need to adjust the "line in" level. You need to adjust the output level. If you can't do it by the audio device, then yes, you can use software. Btw. an attenuator device could be a simple potentiometer or a cheap mixer. Why is the "device" connected to the Linux computer? Aren't you already using software that allows to adjust the output level? It's not unusual that you can't adjust levels using alsamixer, e.g. when using a class compliant USB audio interface. I can't comment on pulseaudio, since I never ever would install it. I'm using either jackd or plain ALSA, but to adjust speaker volume I'm using an analog amplifier. _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
