Is it possible to install it?
Every random page I could find that was gentoo+oss4 related seemed
old. I know the kernel does not support oss4 at all, any more than
portage does, but I don't know whether that means it is impossible to
install.
Anyone using it?
Thanks

Nope. That's just Alsa imitating OSS, maybe to accommodate software
that expects OSS (I may be completely wrong, of course)

I wasn't sure about it either. I was hoping it would provide kernel
modules that could be used or something like that. Might be worth
installing and then doing a equery f alsa-oss and see just what it does
include. If it won't help, uninstall and hope for another option.
Surely there is a way to do this, somewhere. :/

Sure, why not. It installs a wrapper, a headings file and a library.

Maybe, unless it is really blocked by the kernel.

There is this link:
https://wiki.gentoo.org/wiki/OSS
That seems to say you can still install the real OSS.
The first step is to build a kernel with it included:
Device Drivers --->
<M> Sound card support --->
--- Sound card support
< > Advanced Linux Sound Architecture --->
< > Open Sound System (DEPRECATED) --->
Of course, since it is marked DEPRECATED, you don't know how well the
driver will work.

I'm using kernel 5.6.0 (off portage). It doesn't offer the OSS
possibility, deprecated or not: just Advanced Linux Sound Architecture
or nothing.

My card is on-board Intel HD ("product: 200 Series PCH HD Audio"
according to lshw), so I assume it is pretty common...

OSS4 is a set of proprietary patches. You would need support in kernel,
and support at an application level to use it. Not sure if USE=oss will
work with OSS4, but one thing I know for sure is that you would need to
get the patches from 4front technologies. And given that they keep
moving the license... why would you?

I was under the impression that it is open source (contrary to version
3)? Wrong?
>why would you?
desperation? ALSA is 22 years old, and they couldn't find the time to
write documentation. It will not happen. When it works, it works. It
works for me re hearing sound, but no joy with my recently bought
micro. Maybe it's something as trivial as a faulty cable, but the
current plague doesn't make it easier to get a replacement to try...

It was gpl. Then they moved it to proprietary. Then they become
insignificant and changed it back. For me, that's sign enough that I
don't want anything to do with it.

It might have been invented 22 years ago, but that doesn't mean that it
didn't change/improve over that time.
What do you mean "no joy with micro"? Maybe it could be easier to fix
this than use OSS.

I agree, but I was talking about the documentation, not about the
quality of the software.
Check the main documentation site https://alsa-project.org/wiki/Documentation
The first section contains 4 items, the second of which is just a
title (no link) and the 3rd is a dead link... ( actually, not dead,
but leading to nothing; and it says "Linux Audio Users Guide", a name
suggesting its contents are relevant)

I mean I can't record sound (or I can't play it). Probably because I
don't know what I'm doing (see above, Documentation). I have a micro
which connects to an interface via a XLR cable (it works; I can hear
sound through headphones connected with the direct monitor output in
the interface); the interface gets power from the computer via USB
(works); the RCA output of the interface connects to the LineIn entry
in the card. Trying to record with arecord produces a file that yields
noise or silence with aplay. I tried changing stuff in alsamixer...
https://www.amazon.de/-/en/dp/B01C05AL4C/ref=sr_1_5dchild=1&keywords=mikrofon%2Bxlr&qid=1585927073&sr=8-5&th=1
https://www.amazon.de/-/en/gp/product/B00EK1OTZC/ref=ask_ql_qh_dp_hza?th=1
The reasons I asked about OSS4 and not the details about my problem
are: (i) I like to understand what I'm doing (big picture & details)
and (ii) I don't want to be a support vampire
But maybe OSS4 would be no solution at all. However, it seems that
even trying is not an option...
Thanks

I am not familiar with those products. Sorry. All I can say about it is
that there are 2 types of volumes. The ones for playback, and the ones
for capture. (see F4 in alsa mixer). Also see F6 to select the right
sound card if you have more than one. If you have more than one input
(on that card), make sure you select the right one, You can toggle
"capture" with space. Untoggle all of them, and leave on just the one
you use for recording. Set the volume and try again. I hope it works.
If not, maybe people on the forums could be of more help than I was.

Yes, the first step would be to reduce or set to zero the Mic Boost in
alsamixer and adjust the Capture volume. However, noise with arecord is
usually a result of incorrect bitrate?
You could try:
arecord -fdat -r 48 test.wav
Also, make sure any hardware buttons have been enabled and the mic is not
muted. Additional options may be required to use the correct input device and
driver, which can be specified in /etc/modprobe.d/alsa.conf

OK, I tried "arecord -D hw:0,1 -fdat -r 48 test.wav" and "arecord -D
hw:0,2 -fdat -r 48 test.wav". aplay produces noise, in both cases. I
alse tried with -r 44, same result.
## arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: Generic Analog [Generic Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 2: Generic Alt Analog [Generic Alt Analog]
Subdevices: 1/1

## arecord -L

I assume the two capture devices are LineIn and Mic (mono). Correct?
(But why the device numbers 0 and 2, and not 1?)
OTOH,
## arecord -fdat -r 48 test.wav
ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.2.1.2/work/alsa-lib-1.2.1.2/src/pcm/pcm_dsnoop.c:641:(snd_pcm_dsnoop_open)
unable to open slave
arecord: main:828: audio open error: No such file or directory
I didn't use any flags for aplay, because aplay foo.wav works fine
when foo.wav is music from a CD (i.e., not from a micro)

I have /etc/modprobe.d/alsa.conf (not changed) but I have alsa support
built in the kernel, not as a module (could this be a problem?!)

I can't see your USB mic anywhere ...
Both device 0 and device 2 are on the *same* card. I would think an external
device as you posted previously would register on the kernel as a separate
card.
Is dmesg recognising your USB mic when you plug it in?
Do you need some additional driver for it?
Is there some On/Off button on it you need to turn it on with?

Hmm ... I assume "USB Stream Output" is the USB mic, but I'm not sure and the
Output part confuses me.

Years ago I was having problems with alsa. Audio drivers were not as polished
as they are today for Linux. Anyway, I remember contacting some dev who asked
me to rebuild my kernel with alsa as modules and run 'alsactl init', which
would only produce a full output this way. I don't know if this would still
be a problem today and anyway you are not experiencing the same bugs I was
troubleshooting 15 years ago.
So, in the first instance I would look at a USB driver, if needed, from the
output in dmesg.
lsusb -v would also show any
bInterfaceClass 1 Audio
bInterfaceSubClass 1 Control Device
and any fields showing "Microphone".
Finally, have a look under 'cat /proc/bus/input/devices' or similar for any
USB devices, to find out what driver it is using.
HTH.

Humm... The point is: the interface (Behring) has RCA output, which is
connected to the LineIn of the integrated sound card (not an USB
card). On the other hand, it also has a USB output, which is used to
get Phantom Power (whatever that is), which works (when removed from
the USB entry in the computer, the LEDs go off). However: I think the
device (Behring) also works as a USB sound card (which I don'y want to
use).

No buttons in the Mic; there is a button in the interface that enables
the Phantom Power, but it has always been on.

XLR style mics output to too low for sound card inputs, so let's assume the
Behring interface you have is boosting the signal (and since its an
amplifier it gets its power via USB). The question now is whether the
signal on RCA outputs is suitable for a sound card - i'm not sure, but IIRC
i've done this before and it worked.
I'd be inclined to try setting up the Behring USB though - if its a high
end device it will probably sound better.

The MO is STRIX B250F GAMING. I assumed it would be somewhat better
than a USB card (and the Behring model I have is not that high end)
Anyway, I just build (and modprobe'd) the modules snd-usb-audio and
snd-bcd2000, and still no joy:
arecord -D usbstream:CARD=PCH -fdat -r 48 test.wav
ALSA lib /var/tmp/portage/media-plugins/alsa-plugins-1.2.1/work/alsa-plugins-1.2.1/usb_stream/pcm_usb_stream.c:508:(_snd_pcm_usb_stream_open)
Unknown field hint
arecord: main:828: audio open error: Invalid argument

Mainly out of curiosity, have you tried connecting to the mike in
instead of the line in on your sound card?
