I am running MEPIS 7.5 with Debian Lenny repositories on an IBM Thinkpad A21m (P3 750MHz, Sound Fusion CS46xx (more detail in aadebug output, below)). I have had no problems with audio output. Until recently, I have no need for audio input. I can hear the microphone audio (both with built-in speakers and headphones, also both built-in and external microphones). However, the audio does not get to any applications that accept audio input. I have tried with several applications, including Audacity (which I installed specifically to help debug this issue). I have checked all the mixer settings using alsamixer. I also tried altering the settings. Same result. I also tried using aumix. Notable observation: Muting or reducing the microphone in the mixer is heard in the output (that is, if I mute the microphone, then I no longer hear it on the speakers or in the headphones). Also, I have tried various suggestions from both the Audacity website and the ALSA website. Nothing has helped, yet.
