    I also should check headphones jack because it switches off speakers for headphones and it could be broken too, so there is no sound to headphones or speakers.
    P/N for that board is A-1828-964-A and it names V030 MS/SD DAUGHTER BOARD

    THX

    I already exchange this board (btw is IFX-579) and same no sound

    I check all flat cables (measured by multimeter) and still not audio output

    audio icon there and if you play audio level shows but analogue realtek not send to the speakers and headphones.

    I really don't know what can be wrong. I already repaired of 100-ths of VAIO's but this one make me crazy

    probably MBX 237 I dont know

    Hey!
    Welcome all here, this is my first post as I am having exactly same problem with my vpcsb! It also drives me mad, tried everything but still no analog sound by realtek! I just wonder did anybody figure it out what's causing this issue?

    My vaio in first place did not see realtek audio card at all, after messing with the yellow dual layer flex that links daughter board with main one the card appeared in the hardware manager but no sound on the output at all. Forgot to mention, the backlite keyboard is also not working, I wonder is it possible to adress this problem directly to sony? Its just so weird, everything has been replaced apart from motherboard - but mobo shouldnt be an issue as the realtek chip is on the daughter board?
