System Specs: Sony Vaio PCG-F430 PIII 450 192 mb RAM Yamaha YMF-724 sndconfig correctly recognizes the chip type and proceeds to test output. At this point, one of two things occurs. If PNP is enabled in the BIOS, only a brief portion of the test wav is played, and sndconfig continues as expected. However, when PNP is disabled in the BIOS, sndconfig plays the entire wav, but instead of continuing to dialog asking if wav heard correctly, sndconfig play wav over and over. At this point system is locked. CTRL-C does not work. Caps Lock or Num Lock does not work.
Driver problem ; there's a newer driver in the latest 2.2.18pre series that you might try.
