BSD and Darwin derivatives "DesktopBSD 1.6 RC 3 is now available for download from our mirrors or via BitTorrent. This release candidate is considered a large step towards a final release 1.6 with major changes such as: X.Org release 7.2, improving support for modern graphics hardware; NVIDIA graphics driver, providing hardware 3D acceleration for NVIDIA video cards; latest FreeBSD 6-STABLE as base system with High Definition Audio support; support for multiple processors and multi-core CPUs; more up-to-date software packages from the DesktopBSD build servers; many small bug fixes and optimizations. Upgrades from 1.0 and previous release candidates are supported. An additional language CD and 64-bit (AMD64) DVD will be released soon."

"Well like any computer sold in the last 5 years(at least in Korea) there is NO audio card."

This is correct. I bought my last one many years ago but decided not to use the AC'97 crap. Instead, I installed a PCI card with CMI chipset for better performance. As far as I know, the AC'97 and MC'97 do emulate sound cards or modems respectively, creating extra system load for the CPU which has to perform the sound card or modem functionalities.

Maybe it's the same situation with digital audio data transfer via ATA cable - more CPU load? I don't know...

"These are prosumer things now, and AC'97 or HDA audio on-board is more than good enough for most people."

In most cases this is true. For special needs I'm glad to have the option to use other hardware. For example, MC'97 modems do barely support standards which makes them hardly usabe or unusable with modern OSes (e. g. FreeBSD). I'd still prefer a serial modem if needed, such as I prefer a "stand alone" audio card for better performance and driver support.

% dmesg | grep ^pcm ; cat /dev/sndstat
pcm0: <CMedia CMI8738> port 0xd400-0xd4ff irq 16 at device 7.0 on pci3
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <CMedia CMI8738> at io 0xd400 irq 16 (1p/1r/0v channels duplex default

"Again I think it is the case that these tools simply haven't kept pace with computer hardware
development. ;) "

If hardware specific techniques have become standard, software should try to support them. Maybe the ATA audio data transfer has an equivalent at kernel level in order to make it work everywhere? I'll go and investigate.

But on the other hand, downwards compatibility is important. Especially FreeBSD is a great OS to create usable computers even with 150 MHz 586 CPUs (my personal minimum). While the quotient "speed = hardware / software" stays the same with MICROS~1 OSes on recent hardware, FreeBSD is always impressing by speed improvements on the same (!) hardware. That's why it is important to have in mind, thatt older hardware is still in use (just because it works), so abandoning support for this "easy" stuff would be bad. Just think about how great SCSI works with BSD, allthough almost no one seems to use it anymore (I still have to). :-)
