(I subsequently have found the 32 bit drivers and the procedure should be very similar except the files are SP34789.exe and SP34789.cva). Anyway, here is what you do:įirst you need 2 files which ironically enough come from HP, they are SP35558.exe and SP35558.cva They contain the Conexant drivers for Vista 圆4. It appears that this is a very common problem. The solution from HP for my model and Windows 7 was the 'HP Software Advisor' which was 67MB and totaly useless. By the way HP, the Conexant website says that they do not supply drivers even though they make the chipsets 'at the request of the OEM's.' Another post said that HP was not going to supply these drivers for Windows 7. Microsoft and Conexant both said that HP should supply the drivers. I scoured various forums looking for 64 bit Windows 7 drivers for Conexant audio but to no avail. I had been using an SB Audigy PCMCIA card so I am not sure when Audio was really lost however, he noticed it when I upgraded his PC. My son and I have the L2000 laptop that came with 32 bit XP and used the Conexant chipset for Audio.
