Use "aumix -q" to see which of your input channels are set to "P" (play only) and and which are set to "R" (play and record). If an input channel is set to "P", then you'll hear it out of the speakers, but you won't be able to record from it. If it's set to "R", then you'll be able to do both. My guess is that your "line in" is set to "P". You can change it with a command like "aumix -l R" (case is significant). >When i record from the mic port, it sounds horrid. The default in Linux is to use 8-bit sound, which intorduces a lot of low-level distortion because the granularity is just too low. Using basic commands like "cat" or "cp" will most definitely use the default, so they're not the best way to go. Use a command which lets you specify the sample size, and use at least 16 bits. -- Dave Mielke | 856 Grenon Avenue | I believe that the Bible is the Phone: 1-613-726-0014 | Ottawa, Ontario | Word of God.
