The chip is a Snapper, and microphone recording used to be supported. Debian package alsa-utils 1.0.11-2 is installed. $ cat /proc/asound/cards 0 [Snapper ]: PMac Snapper - PowerMac Snapper PowerMac Snapper (Dev 38) Sub-frame 0 $ cat /proc/cpuinfo processor : 0 cpu : 7447A, altivec supported clock : 533.333000MHz revision : 0.1 (pvr 8003 0101) bogomips : 36.73 timebase : 18432000 platform : PowerMac machine : PowerBook6,5 motherboard : PowerBook6,5 MacRISC3 Power Macintosh detected as : 287 (iBook G4) pmac flags : 0000001b L2 cache : 512K unified pmac-generation : NewWorld ====================================================================== ---------------------------------------------------------------------- bz31 - 06-10-06 18:56 ---------------------------------------------------------------------- Hi, I found how to record ! I must use two channels. One channel doesn't work. Using rec: $ rec -c 2 test.wav $ play test.wav Using audacity: Edit ---> Preferences --> Channels: 2(stereo) Then I can record from microphone Note: In audacity, when recording, I see L R ----- the input level meter. Only Right channel R works. The Left channel dosen't works. Maybe this is why we can't record mono sound. ---------------------------------------------------------------------- piem - 06-12-06 17:03 ---------------------------------------------------------------------- i know the microphone is mono, but i still can't capture at all. Bin, what kernel / alsa versions are you using?
