Re: [Studio-users] Not able to record

[Nick B. <n.j...@el...>]

Just a thought...

Studio uses the oss interface, because it is a very old program and ALSA 
was very immature when it was written (and it isn't now? All my 
computers have just had their sound broken completely *again* so I'm not 
apologing for sticking to OSS, esp as I don't need real-time response. 
Grrrrr... Spot the debian user :)

If you are using ALSA, you will need the pcm-oss module loaded. If you 
do /sbin/lsmod, is it there? I would have thought so, because you say it 
starts up without complaint and plays wave files. If this is the case, 
/dev/dsp must be fine.

I will think about alsifying Studio as soon as ALSA actually document 
anything. Hell, I'll even start teaching it in my course!

Meanwhile, when I manage to get any sound back on my debian Sid systems, 
I'll take a further look at what's going on here. If you are really 
stuck and need an editor desperately, you can always resort to audacity 
if it is packaged for your distribution. Of course, you won't get all 
the excellent features of Chris' Sox program, but at least you can 
record/edit/save with it (and rather well, as it happens).

Sorry to be so useless at the moment.
