Greetings: I've switched my laptop back to Planet C's RH9 and its 2.4.26 kernel. The machine is much happier now. However, a problem has come up that did not exist on a former identical installation: My PDAudioCF card is not recognized when I 'cat /proc/asound/cards'. lsmod shows this report: [dlphilp@localhost dlphilp]$ lsmod |grep pdaudio snd-pdaudiocf 10980 0 (unused) snd-ak4117 7196 0 [snd-pdaudiocf] snd-pcm 85952 0 [snd-pcm-oss snd-pdaudiocf snd-ak4117 snd-usb-audio snd-cs4231-lib] snd 48708 0 [snd-pcm-oss snd-mixer-oss snd-seq-dummy snd-seq-oss snd-seq-midi snd-opl3-synth snd-seq-instr snd-pdaudiocf snd-ak4117 snd-usb-audio snd-virmidi snd-seq-virmidi snd-seq-midi-event snd-seq snd-cs4232 snd-opl3-lib snd-hwdep snd-mpu401-uart snd-rawmidi snd-seq-device snd-cs4231-lib snd-pcm snd-timer] ds 8776 2 [snd-pdaudiocf serial_cs pcnet_cs] pcmcia_core 57504 0 [snd-pdaudiocf serial_cs pcnet_cs ds yenta_socket] But catting proc shows only: [dlphilp@localhost dlphilp]$ cat /proc/asound/cards 0 [CS4231 ]: CS4231 - CS4231 CS4231 at 0x534, irq 5, dma 1&0 1 [VirMIDI ]: VirMIDI - VirMIDI Virtual MIDI Card 1 2 [M2x2 ]: USB-Audio - Midisport 2x2 Midiman Midisport 2x2 at usb-00:07.2-1.2, full speed I added these lines to /etc/modules.conf : alias snd-card-3 snd-pdaudiocf alias sound-slot-3 snd-pdaudiocf I also tried manually loading snd-pdaudiocf, it seemed to work all right and reported no error. Nevertheless, no PDAudioCF card appears in /proc/asound. The card's little blue light is on, indicating that the card is recognized by the PCMCIA system, but something else is wrong somewhere. Any suggestions ? Best, dp
