I`ve just updated my Ububntu form 9.04 to 9.10....after the restart I cannot find my sound card and the driver for my video isn`t working????

I`m running it ot Acer ASpire 5738G with ATI HD4570 video and the audio was some ALC888 i think...

EVERY time after update ....i don`t know what to say...

Can someone help me because i`ve tryed to reinstall the packages - no luck...
