Above you see a snd_ens1371, this should be the ALSA module for your sound card

Here you see a es1371, i'm not sure, but this seems the OSS module for
your soundcard and both, ALSA and OSS, are loaded. I've read that with
the recent ALSA Sarge packages this behaviour is corrected, but you
can avoid this inserting a line in your /etc/hotplug/blacklist with
"es1371". This should be enough.
