Onboard Sound via the ES1938s

es1938s
What you need: The alsa drivers, libraries and utilities from www.alsa-project.org. RC1 used for this document. Kernel level support for sound: CONFIG_PNP CONFIG_ISAPNP CONFIG_SOUND
What you do: Compile each of the alsa packages; in order. You may also want to pass the "--with-cards=es1938" option to configure in the driver set. Run the "snddevices" script in the drivers directory; this ensures you have the correct dev entries. Edit /etc/modules.conf to add the following entries: alias char-major-116 snd alias char-major-14 soundcore alias snd-card-0 snd-es1938 alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss Run "alsamixer" and set the sound levels that you want; "alsactl store" will save them.
Notes: The kernel esssolo1.o driver may work; testing hasn't shown it to be reliable, however.
