I'm normally a server person but I'm now trying to record some audio and I'm a bit stuck on how the Linux sound system works. I've read the Mini How-to, but I still can't figure out what is happening.
I have a Thinkpad T22 and the soundcard is detected as:
Sound Fusion CS46**, Chip Cirrus Logic CS4297A rev 4.
I am running Ubuntu 6 (Dapper Drake)
I am wanting to record some audio from the Line-in port of the laptop. This is taking some piano music from a tape, with the intention of converting it to CD / MP3.
The sound is coming in OK as I can adjust the sound levels so that it can be heard through the speakers, but I am unable to record.
I've tried using the "Sound Recorder", which just hangs whenever I try and use it, and Audacity, which tries to record, but is just empty.
I have adjusted the line volume in ALSA Mixer (which affects the sound coming out of my speakers, but not the recording).
Distribution: Xubuntu 9.10, Gentoo 2.6.27 (AMD64), Darwin 9.0.0 (arm)

I'm thinking you don't have oss emulation working. oss is the old system. /dev/dsp & /dev/mixer are oss and this is depreciated in the 2.6 kernel. /dev/mixer isn't an audio io it just controls the mixer. alsa is the new sound system, but since some programs (like audacity) only support oss alsa has an oss compatibility layer (but yours may not be enabled) when I sugested ecasound it was because it is a very versatile program that supports many io options including alsa try:
