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.Regards,Anders
I just tried and indeed the -s option ignores the -l option, so there is just one shot no matter what.
I suggest preparing multichannel wav files with all channels except one silent (using e.g. sox) and use the wav file input option for speaker-test.
I would love of future version of speaker-test to let the -s option take the -l option into account!

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

I am using alsa speaker-test to set my channel gain levels
with a spl

follow command
line -
speaker-test -Dhw:PCH -c 6 -s 1
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.
