Esteemed Colleagues:
As you may recall, my computer is a multiboot machine, on which
several different operating systems are installed, which enables me to
compare how different systems manage identical hardware. You may also
recall that my attempt to integrate my Linux and Schillix systems by
placing shared directories (e.g., /export/home/jay, or /opt/assp) on
ZFS has permenantly driven me off my Linux system, as installing ZFS
on my Linux system crippled it, it can no longer stay functional for
more than a few minutes. Apparently, installing native ZFS on a
32-bit Linux system with 256 megabytes of memory is not a good idea.
When I had to start using my Schillix system exclusively, one of the
more visible losses was the loss of my sound device. Judging from the
external ports on my computer, I have two audio devices, one seems to
be on the motherboard whereas the other is a separate card. My Linux
system was able to recognize one of my sound devices, namely, the
external card; my Schillix system is not. There is no /dev/audio.
Here are the relevant lines from the output of prtconf -v:

I do not know whether the above describes the audio device on the
motherboard, which my Linux system did not see, or the audio device on
the separate card, into which my speakers are connected, which my
Linux system did see; prtconf only describes a single audio device.
The point is that I had sound on Linux, but I do not have it now.
This is, parenthetically, quite annoying, because I expect more from a
Solaris-derived operating system; Solaris is supposed to be a serious
operating system, not a toy. In contrast, I recently installed SkyOS
on my computer, and SkyOS is a tiny operating system, the entire
operating system fits on a single live CD, and it was from the live CD
that I installed it. When I boot SkyOS, the speakers play music.
Even a tiny toy operating system like SkyOS is able to find and drive
my audio card, but Schillix cannot.
That is not, however, the sole reason why I write. The reason why I
write is that I recently bought a headset with both audio and USB
connectors. There was no point in using the audio connectors, but I
attached the headset to a USB port using the USB connector, and, to my
surprise and short-lived delight, I now have a /dev/audio. Here is
the relevant output from ls -l:
First, before sticking in the USB connector:
$ ls -lRa /dev/audio* /dev/usb*
ls: cannot access /dev/audio*: No such file or directory

However, although I now have a /dev/audio device, that fact is not
(yet) of any use to me. Specifically, when I stick the USB connector
into a USB port, and put the headphones on my head, and then cat a .au
file onto /dev/audio -- e.g.,
$ cat /opt/demo/sound/does_not_compute.au > /dev/audio
I do not hear intelligible sounds, I only hear an unintelligible
chirping. I do hear something, and after more than a year without
sound on my Schillix system, it is encouraging to hear an
unintelligible chirp, but it is not useful.
Thus, it seems that I have two questions:
1. Are there any kernel drivers I can obtain from anywhere, and then
modload into my system, that will enable it to recognize the audio
card that my Linux and SkyOS systems can recognize?
2. Regardless of whether I can make my audio card functional, what
must I do to obtain a functioning /dev/audio with my USB
converter?
As always, thank you in advance for any and all replies.
