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 

All I did was read the man page. It says that if you use -s it only plays
once. No matter what -l says. Ie the man page says that -l only works for two
channel. Butr maybe the man page is wrong? I do not know.




Ah, ok, that may well be true - I interpreted the manual as saying the just using -s option would always just do one-shot, so -l would be needed to increase the number of repetitions. I did not try it myself, but will do so as soon as I have opportunity and report back.

      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 speakers

            everything works fine and I hear pink noise from the front

            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.
