Where in this document does it tell me how to test the device nodes? Not even in the troubleshooting section.
Hope to see a fix to the docs.
Thanks.
14.4 Creating and Testing the Device Nodes
After you reboot, log in and run dmesg | grep pcm as shown below:
# dmesg | grep pcm
pcm0: <SB16 DSP 4.11> on sbc0
The output from your system may look different. If no pcm devices show up, something went wrong earlier. If that happens, go through your kernel configuration file again and make sure you chose the correct device. Consult the troubleshooting section for additional options.
If the previous command returned pcm0, you will have to run the following as root:
# cd /dev
# sh MAKEDEV snd0
If the command returned pcm1, follow the same steps as shown above, replacing snd0 with snd1.
Note: The above commands will not create a /dev/snd device!
MAKEDEV will create a group of device nodes, including:
Device Description
/dev/audio SPARC-compatible audio device
/dev/dsp Digitized voice device
/dev/dspW Like /dev/dsp, but 16 bits per sample
/dev/midi Raw midi access device
/dev/mixer Control port mixer device
/dev/music Level 2 sequencer interface
/dev/sequencer Sequencer device
/dev/pss Programmable device interface
If all goes well, you should now have a functioning sound card. If you do not, read the next section.
