Yes I can confirm that:
Pactl unload-module <index>
stops the sine output on both channels.
But in
pactl list modules short
the module<index> has disappeared while the other module-sine is still
there.
This definitely should not happen. I'll investigate and see if I can
reproduce the issue.
Could it be related to t he other modules that are loaded after boot?
Here is a list of all modules that are loaded in my case by default:
pi@TEST:~ $ pactl list modules short
0 module-device-restore
1 module-stream-restore
2 module-card-restore
3 module-augment-properties
4 module-switch-on-port-available
5 module-udev-detect
6 module-alsa-card device_id="0" name="platform-soc_audio"
card_name="alsa_card.platform-soc_audio" namereg_fail=false tsched=yes
fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes
card_properties="module-udev-detect.discovered=1"
7 module-native-protocol-unix
8 module-default-device-restore
9 module-rescue-streams
10 module-always-sink
11 module-intended-roles
12 module-suspend-on-idle
13 module-console-kit
14 module-systemd-login
15 module-position-event-sounds
16 module-role-cork
17 module-filter-heuristics
18 module-filter-apply
Annother hitch is that it takes quite an amount of time after
unloading before module-sine can be reloaded again (roughly 10secs).
This also sounds weird. Same comment as above.
Is there any flag or indication that the unloading has completed so
that the module can be reloaded again?
Kind regards

I want to use MODULE-SINE to produce two independent sine wave

a sound card:
By using :
pactl load-module module-sine frequency=1000
I get of course the same 1000Hz signal on both channels and
pactl unload-module module-sine stops both of them.
So the question is whether there is a configuration to start and
stop left and right channel independently and to run them with
different frequencies?
Thank you in advance

You can use module-remap-sink to create independent sinks for each
channel.
Then you can use module-sine on the remapped sinks.
