Zdravim,
trapim sa s nasledovnym problemom. Mam laptop IBM ThinkPad Lenovo Z60m. Zvuk mi
v pohode prehrava aj cez zabudovane reproduktory aj cez sluchatka. Nefunguje
mi vsak mikrofon. Ak tam nastartujem Windows, mikrofon zacne fungovat.
Stiahnutou hlasitostou to asi nebude, aumix aj alsamixer, alsactl som skusal.
Moj kernel je 2.6.17, lspci:

Toto su potencionalne zvukove zariadenia v /dev. Nahravat zvuk som skusal takto:
sound-recorder -c 2 -A /dev/dsp -S 00:05 -b 16 -f wav test.wav;
ale nahra to tam maximalne elektronicky sum. Namiesto zariadenia /dev/dsp som skusal aj /dev/adsp, ale vypise to
