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=20
/dev/audio SPARC-compatible audio device=20
/dev/dsp Digitized voice device=20
/dev/dspW Like /dev/dsp, but 16 bits per sample=20
/dev/midi Raw midi access device=20
/dev/mixer Control port mixer device=20
/dev/music Level 2 sequencer interface=20
/dev/sequencer Sequencer device=20
/dev/pss Programmable device interface=20
If all goes well, you should now have a functioning sound card. If you =
do not, read the next section.
