Re: How does one record audio?
If it use to work under Linux but no longer, are sure you hardware is ok. Have you ever been able to play any audio files? Also, you have to use mixer to adjust the input level and the recording source. See man mixer. Sounds like a hardware or configuration issue. Also there is a Windows version of the Audacity which I have used under Win2k it works nicely. Oh, I guess that begs the question does the same hardware setup work under windows?? If it does, then expect it to be a configuration issue with your sound setup [I have no idea if your sound chip is support under Freebsd and I haven't used 5.1, So someone else will have to answer that]. Have you searched the freebsd mail archive of questions, stable, and current. also does the device show up in your boot messages? Sorry but in a rush, David RexFelis wrote: I am using FreeBSD 5.1-p10, and recently I have need to record spoken sounds. I have installed Audacity from ports, as well as KRec, but neither of these works. Audacity shows nothing but silence for the waveforms. The KMix applet menu in my taskbar shows the microphone as having no volume, presumably because there's something not properly connecting somewhere software-wise. The microphone is plugged in. My motherboard is an Albatron KX400+ Pro, and I am using its on-board audio, which is a 6-channel capable Realtek ALC650 chip. This chip responds beautifully to the 'device pcm' line being added to the kernel config file. It does nothing for the recording capabilities. A perusal of the handbook revealed almost no mention at all about recording audio, and certainly no mention I could find about actually doing it. It did mention adding 'device csa' for crystal sound cards, and I thought the chip was a crystal chip, but doing this has not had any effect. A google search turns up nothing but a few other people asking the same question I have: How do you manage this? bsdforums.org has some stuff about this, but it's only talk that suggests that others have working audio recording in place; there is no mention of how to do this. I have even tried plugging the microphone into the other possible jack. I need to record a CD for someone, of me speaking. I really don't want to do this under Windows, and while Audacity under Linux worked for a short time, it now only produces static. Something is obviously broken there. Does anyone have any ideas how I can get this working? Have I left any information out that might have been useful? I appreciate your help on this matter. Shannon __ Do you Yahoo!?

As DavidB said, the fact that it no longer works in linux implies that you might have a hardware problem--with the sound card, or even with the mic. (Is this the same mic you used in linux? Otherwise, it may just be something simple, like impedance or preamping.) However, there's one more easy possibility to check: Make sure the mic isn't muted. From aumix, or your favorite oss mixer app (I think this is what kmix is, if I remember correctly), and check/play with the level and mute settings for mic, record, line in, or anything else that looks like an input. In addition to the level and mute settings, you may also see a record source setting--with most setups, you can select exactly one recording source, so try selecting each of them in turn; with others, each one can be turned on and off separately. You may also have a master record level and mute setting to play with. While you're at it, see if you can record from the CD (through the soundcard, assuming you have an audio connection--generally a little 2-pin cable--between the two; digital CD audio extraction won't tell you anything useful). You may also want to look at the sysctl settings to see if anything looks fishy. Try sysctl -a |grep snd to look at what knobs you have and what they're set to. I've noticed that when I have hw.snd.pcm0.vchans set to anything 1, this sometimes interferes with audio input (but then I'm not sure my ancient fm801 is full-duplex). If fiddling with the mixer and sysctl produces no effect, you're probably best testing either in Windows, as DavidB said, or with a clean copy of linux (maybe even use a different distro). By the way, if you're not sure which sound card you have, use lspci (/usr/ports/sysutils/pciutils--or run the binary from your linux distro, or reboot to linux) and it should tell you something like this: 00:04.0 Multimedia audio controller: Falcotronic, Inc Komissar 2000 [CHA] (rev b23) This implies (though it doesn't guarantee) that the driver you need is snd_cha--and it provides enough information that some helpful soul can tell you exactly which driver you need. However, most likely this won't help; if the sound output is working, the correct driver is probably already being loaded as a module (scan kldstat's output for snd_*.ko). ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
