ukiwa below Win 7 waeza pata shida kupata accurate driver itayofaa katika machine yako
cha kufanya ni nenda kwenye Device Properties, capture jina la Sound Card, then ingia google search kwa syntax hii
<sound driver card_name OS_version HP>
glance kila result uliyopata, ukijaribu kudownload na kuinstall, hope full utaipata yenyewe
tegemea sana site yao HP, hapo kuna categories na OS na sound_card
all the best
