Hi I was trying to use ctl_elems hooks with dmix plugin but figured that this combination doesn't work. Is there any workaround for this. I am trying the following. There are two softvol devices s0 and s1 going through dmix plugins. I wan't to mute s0 when any app opens s1 and unmute s0 when s1 is closed. I am using the below asoundrc file which results in "No card for this PCM" . Any workarounds or any minor change in libasound which will make this work?

Currently hook plugin doesn't work with dmix/dsnoop. The problem is that it doesn't inherit the result of snd_pcm_info() from the slave PCM. It'd be not too difficult to make it working, though, I guess.
