Just wanted to express my happiness with oss4.

I tried installing it in the past, i could not get it to work then. (forgot what went wrong)
I gave it another try today..It all installed ok, via the overlay. Very good sound quality!
Until today, i had to switch to windows for best hifi sound. This is no longer the case.
Vlc, mplayer2, ffmpeg, audacious all working fine.
Using asus-ST card with sennh. hd600.

I guess there are still some compatibility-issues with some programs, but these don't seem to affect me much.

Since the HD600 are headphones, did you try bs2b while in ALSA?

No, i did not try bsb2 with alsa, so i can't really say anything about it. I just read about it, the theory behind it seems plausible.
My experience however is, (& i have a lot of hours listening to headphones with different sound-cards) that no plug-in/effect etc. sounds good to me. Just stereo, with a little eq in windows (i find the bass too heavy/dominant without eq in windows with this op-amp/card/phone). With the hd595 the flat eq mode is just right for me.
No cross-feed, crystalizer, cms3d (on xfi, an awful effect for music, not games), Dolby headphone etc. I hate it all.
And it is not my goal to talk bad about alsa. I used it until now (& i will probably use it again if when "upgrading", oss4
doesn't seem to work again for some reason).

Alsa has always worked without trouble.

But: comparing to windows & oss4 it sounded: more flat, more dry, just more "dead".

Pennypacker ...

I also have Sennheiser HD600 and generally don't like any kind of filtering, however I was impressed with bs2b, its somewhat of a subtle experience, and I now find stereo in headphones "distracting" (at least thats the only description I can come up with).

In the OSS4 configuration, did you specify headphones?

Maybe OSS4 automatically applies something bs2b-like?

Yes, maybe there is something like bs2b already included in the windows or oss4 drivers..

I just selected "headphone" in ossxmix "CMedia CMI8788" x-panel. There was no need for much configuration-file editing.
Looking at /usr/lib64/oss/etc/devices.list, i see that all xonar cards, except the ST, have an entry in there.
Guess i'm using the "stock" cmi8788 driver, which works fine.
Choosing between the 3 headphone-gain settings is not (yet?) possible, but i don't mind this.
The "field of sound" is a little different from windows..there seems to be a bit more bass, but not in a fatiguing way.

Still i would like to be able to turn the bass lower..

Is there a "normal speakers" output selection, that you can test? If it sounds "more dead" through headphones, then we have the answer :)

Is OSS4 MIDI capable ?
I left FreeBSD for my desktop a couple of years ago because FreeBSD was OSSonly and OSS was not MIDI capable.

Moved from Multimedia to Unsupported Software. I was reminded by one of the developers that Oss4 is not yet in the official tree, so this thread fits better here.

Oh yes it does, well I mean it can play a midi file but it just cannot honestly manage the MIDI port of your hardware device => The plugging of a keyboard or any MIDI aware external instrument is simply impossible. In some rare cases you can but must face so huge latencies that you'll just give up.

The ebuilds are really old in the overlay with oss-4.1.1052, current versions:

I have newer ebuild in my overlay plus a live one (a failure to clone the mercurial repo is not an exception, syncing to it is already too much hassle). Anyway, 4.2.2006 is available.

Another way to improve the ALSA output seems to be to compile mpg123 with --enable-int-quality, as done in Arch. I notice that Gentoo doesn't have this option - someone wanna file a bug? (I'm not a Gentoo user.)

mpg123 is used by both mplayer and audacious, which the OP mentions.

I just upgraded to kernel 3.5 & audacious 3.3. (with, as before, oss-devel-9999)
Could i be imagining things?..but my opinion is, that music quality has improved again.
Quality is superb now, i think. (most stereo headphone listening).

Very good, Thank you devs! -)
