There is only the one directory, /proc/asound/card0/codec97#0. The contents are included below. The interrupts in /proc/interrupts do increase for the sound card while a file is playing. Where do I toggle the external amplifier power down?

I need contents of all files in /proc/asound/card0/codec97#* directories.
Also, look if interrupts are increased in /proc/interrupts file while you
play some file.


Also, there is 'External Amplifier Power Down' control which might affect
the playback (try toggle this switch while playing).
