rec from vmix loop works only first time after oss startup

[konst1089]

Hello,
I have a problem with recording from vmix loop device. As described here, ossrecord, or recordmydesktop, or just cat /dev/oss/oss_sblive0/loop0 > somefile work fine first time after oss startup (or restart), but then loop0 becomes producing only constant loud noise with little artefacts. I have Creative Audigy 4 sound card which hasn't hardware mixer, and have to use vmix loopback devices or something else to record sound from apps.
Is it reproducible on other systems (mine is Ubuntu 10.10 64bit with 3.2.0-rc5 kernel, oss 4.2 build 2006 from hg, Audigy4 (oss_sblive drv), alsa and pulse are completely removed), or is there any simple and good solution to avoid this problem?

"loopback" is a kind of PulseAudio.

If you are not a masochist, you may better try a cheap soundcard which has "hardware mixing" with OSS4.

If I am not mistaken, the general situation is about as follows:
1. New professional soundcards do not have Linux drivers.
2. Ancient soundcards (before 2000) have HW mixing with Linux drivers.
3. Newer souncards (from 2004) do not have HW mixing with Linux drivers, because Linux is PulseAudio (by definition).

Intel HDA standard was created in 2004 http://en.wikipedia.org/wiki/Intel_High ... tion_Audio
Intel HDA soundcards (e.g. Intel HDA ICH7) are not likely to have HW mixing with Linux drivers.

AC'97 (short for Audio Codec '97) standard was created in 1997; soundcards: Intel ICH, ICH2, ICH3, ICH4, old VIA, and the like http://en.wikipedia.org/wiki/AC'97
Such soundcards have HW mixing with Linux drivers.

The Envy24 chipset was developed before 2000; soundcards: ICE1712 and the like http://en.wikipedia.org/wiki/VIA_Envy
Such soundcards may have HW mixing with OSS4 (I have not tried them yet).

You may ask somebody whether envy24 soundcards have HW mixing with OSS4 or not.

I think setting up one option in the config file isn't any kind of masochism. I really don't need to record something every day (especially from sound mixer). And don't care much about quality of such records (I tried to record some moments from a game to share with friends). Recording from other sources (line in, ac97) works. OSS provides the best sound quality for playing music with my soundcard (compared with Windows native driver, Windows KX driver, Linux ALSA/Pulseaudio), that is why I use it. And I think it's a bit inconvenient to have Pulse only for such little work or even change my sound card. Thus I'm searching for another solution.

You told that you need a "simple and good solution". Right?
The simplest and the best solution is a soundcard with HW mixing. Just check "rec" under the "vol" (see the screenshoot above) and everything will be recorded (microphone, playback, etc.). Any other solution is not simple.

You may try JACK. It was working with OSS4 in 2009. Today it may need to be recompiled and patched, perhaps viewtopic.php?f=3&t=4452#p17854
You may also try to find an old deb-package and its source code:
http://packages.ubuntu.com/hardy/jackd
http://packages.ubuntu.com/hardy/qjackctl

Have you already tried to recompile Ubuntu packages using the Debian Build System?
If not, you may try this manual http://www.4front-tech.com/forum/viewto ... =15#p13781
It is much easy, of course, to solve such problems with Arch Linux (for example: http://www.opensound.com/forum/viewtopi ... =30#p15703 ).

I have the same problem and I can't figured it out. I've attached screenshot of my ossxmix. Could you tell what should I change. When I run the ossrecord desktop.wav the output result is very quiet with lots of static noise. Using the loop device I get recording wihich is loud, but not clear.

I'm also wondering about recording sound in general (not only with ossrecord). Should I make another thread for that.

Should I make another thread for that.

Yes. You may post the output of "ossmix", "ossinfo", "lspci -v"

When I run the ossrecord desktop.wav the output result is very quiet with lots of static noise.

This may happen, if you have wrong settings. The correct settings might be found by the method of "trial and error" https://wiki.archlinux.org/index.php/OS ... io_devices
You have to study your "ossinfo" to find out which "recording devices" are available. Then you can run a magic command like this:

Code: Select all

$ ossrecord -vl - | ossplay -

or (if "3" [/dev/dsp3] is your recording device)

Code: Select all

$ ossrecord -d3 -vl - | ossplay -

and try different settings in the mixer.

The first step is to switch off "internal speakers".
You have to use analog earphones to avoid "auto-oscillations".
It makes sense to try both internal and external mics (one of them may not work).

In a word, Sennheiser PC 131 Headset works wonders, but it is not robust and can be easily broken. The quality of recording is incredibly good. The mic is uni-directional, only your voice is recorded, all noise around is cancelled, no noise removal is required. The signal is so strong that you do not even need to remove the evil 50Hz (or 60Hz in US) in the recordings (but you have to remove DC offset, of course).
http://www.sennheiserusa.com/headset-ph ... sic-500912
You may try more expensive Sennheiser (analog) headsets. The key words are: perfect for voice recognition.

This command produces only a very loud noise:

$ ossrecord -vl - | ossplay -

That noise almost disappear when I set fp-green to mute, but then sound from my music player goes very low. The best result is still when using the loopback device, but only for one sound at time. Playing two sounds results in unclear recording.

[igorzwx]

This command produces only a very loud noise:

Code: Select all

$ ossrecord -vl - | ossplay -

It is perfectly O.K. It also produces a very loud noise on my Dell notebook, if the internal speaker is on.
EXPLANATION: It seems to be "auto-oscillations", or, more precisely, a kind of "non-linear resonance"
http://en.wikipedia.org/wiki/Resonance
A similar phenomenon may happen if two Linux/OSS4 users speak by Skype (skype-oss) and both use external speakers and omni-directional microphones (such as "internal mic" or ordinary external microphones). To avoid such troubles, you have to use earphones (if the so-called "echo-cancellation" is not available).

The true secret of the ancient magic ritual of "trial and error": If you apply the method of "trial and error" and observe a strange phenomenon, such as "a very loud noise", you have to try to find out the reason (cause) for it, or, at least, to create a kind of explanation in the form of quasi-scientific mythology (such as "quantum theory", for example). Otherwise, it is a kind of "stupid business" rather than a scientific ritual of "trial and error".

To switch off the internal speaker, I have to change "jack.int-speaker.mode" to "input".
When the internal speaker is off, I can record with the internal mic. Sound quality is good.
You may post the output of your "ossmix" (on terminal).

It is very probable that your mic is already working, you may only need to switch off the internal speaker.

[Matti]

That's what ossmix outputs in the terminal:

Have you enabled all switches with oss_hdaudio config? Or it is your "default mixer"?

jack.fp-green.mode <front|rear|center/LFE|side|pcm4|input> (currently front)
jack.fp-green [<leftvol>:<rightvol>] (currently 29.9:29.9 dB)
jack.fp-green.mute ON|OFF (currently OFF)

You may try to change jack.fp-green.mode to "input" or "rear", or else, instead of muting it.
You told that "jack.fp-green.mute" somehow affects your "noise". Right?

That noise almost disappear when I set fp-green to mute, but then sound from my music player goes very low.

[Matti]

That is my default mixer settings. I didn't change anything.

I see in the oss_hdaudio manualthat fp-green is for front panel speakers (I have headphones pluged there with detached microphone). Setting that to input results in no sound from music player. Setting fp-pink to input still gives me noise when running ossrecord -vl - | ossplay - command.

[igorzwx]

That is my default mixer settings. I didn't change anything.

You may try to experiment with "jack.fp-green.mode", see my previous post.
Perhaps, "input". And see how it affects your "noise".

You may also try "fp-mic" here:

Code: Select all

misc.input-mix <mic|fp-mic|linein|int-cd> (currently mic)

[Matti]

I have changed fp-pink to input and misc.input.mix to fp-mic and now running

Code: Select all

$ ossrecord -d7 -vl desktop.wav

produces output that I can hear. Though it's very bad quality.

[igorzwx]

I have changed fp-pink to input and misc.input.mix to fp-mic and now running

Code: Select all

$ ossrecord -d7 -vl desktop.wav

produces output that I can hear. Though it's very bad quality.

It is already a "good step forward".
You may also try to use the "earhpnes jack" for mic and other way round.
Set jack.fp-pink.mode to front and plug your earhpnones to the "mic jack",
and plug microphone into the earphones jack and "jack.fp-green.mode" to "input".

For "misc.input-mix", it makes sense to try mic, fp-mic, linein.
You have to find out which switches affects the quality of recordings.
It might be reasonable to "mute" or set to zero everything which you do not need.

1. STANDARD: mic → mic jack, earphones → earphones jack

Code: Select all

jack.pink.mode <front|rear|center/LFE|side|pcm4|input> (currently input)
jack.fp-pink.mode <front|rear|center/LFE|side|pcm4|input> (currently input)
jack.green.mode <front|rear|center/LFE|side|pcm4|input> (currently front)
jack.fp-green.mode <front|rear|center/LFE|side|pcm4|input> (currently front)

2. REVERSE: mic → earphones jack, earphones → mic jack

Code: Select all

jack.pink.mode <front|rear|center/LFE|side|pcm4|input> (currently front)
jack.fp-pink.mode <front|rear|center/LFE|side|pcm4|input> (currently front)
jack.green.mode <front|rear|center/LFE|side|pcm4|input> (currently input)
jack.fp-green.mode <front|rear|center/LFE|side|pcm4|input> (currently input)


But you also have:

Code: Select all

misc.input-mix <mic|fp-mic|linein|int-cd> (currently mic) → mic, fp-mic, or linein
misc.front1 [<leftvol>:<rightvol>] (currently 46.4:46.4 dB)
misc.front2 <front|input-mix> (currently front)

"misc.front2" is likely to be your "front-panel mic".
You may try to set it to "input-mix".

Notice that there are other "mics" to try:

Code: Select all

misc.rear2 <rear|input-mix> (currently rear)
misc.side2 <side|input-mix> (currently side)

It might be possible to use "rear/side" as "front" or "mic".

[Matti]

I've didn't manage to go further (the quality of recording is still very poor). Changing jack.fp-green.mode to input results in no sound from my music player (it's control for the front panel speakers). The second thing (jack.fp-pink.mode) is for front panel mic/line-in (microphone or line in).

Maybe I'm trying to use inappropriate tool for the job. I want to record sound from applications like games (native and wine), music players and other things.

Anyway this is current state of my mixer:
