Actually, I believe disconnecting anything should be unnecessary?
If speaker-test -Dhw:PCH -c 6 -s 1 already works, adding infinite loop option should suffice?
speaker-test -Dhw:PCH -c 6 -s 1 -l 0

man speaker-test ?if -s is used the program will always only produce a single shot.SO use -l 0 (loop indefinitely)and unplug one of the speakersOn Sat, 12 Sep 2015, Alan Bromborsky wrote:I am using alsa speaker-test to set my channel gain levels with a spl

everything works fine and I hear pink noise from the front left speaker,
but the tone doesn't last long enough to set the channel gain using my
spl meter. Is there anyway to make the duration of the tone (pink
noise) longer. Fifteen seconds would be sufficient.
