question #1 did you change the OS from new day 1,
for example upgrading to W10? if yes, HP does not support this.
forget DELL this has nothing to do at all with DELL ever.
Google can't fix machines of any kind
, in fact google
gets you like 1 million guesses, or lies and all are at best worse than tossing a coin or guessing your self. a fact.
It is the Disinformation age
, and gets worse every day.
what does work, is diagnoses not guessing or reading endless posts by others, most of which lack any facts worth knowing.
like yours what OS is there windows what????????
My first guess is the internal speakers are dead.
As are $1 earbuds dead.. as the next test.
why not tell the helper first, what you are attempting.
? sound tells me zero, tell what you are doing
like this. ( one guy cant watch movies online, 2nd cant play a local sound wave file or mp2 and guy 3 cant get windows sounds working. see?
DO BASICS first , first walk then run, see?
I go to control panel, and click sound
then make sure speakers is tuned on here, first.
then click SOUNDS.
then pick Asterisk, and the test button goes green below.
(this works from windows 3 to now)
if not green arrow that means the driver is missing. (or corrupted winds or virus infected)
if the green botton glow and click it and you hear sounds now
then the driver is working.
if this test passes, the we go to the next level of complexity
the sound player, must work (I use VLC and others)
now the driver, at HP, why not ask at HP and not fixya,
HP has support for you unstated OS.
this exact PC came with Linux or Windows
so my guess #1 is windows, sigh.
then guess #2 is windows 7 64bit
and I land here, in 5 seconds flat. amazing no?
the chip is IDT and is problematic
does device manager show errors in the sound chip?
if yes and you run w7 , all drivers are above,
even for XP and VISTA.
try posting what PC ,ok you did,
the what OS you run, you did not.
then tell what you are attempting to do with sound.
lots of things do sound ,name one that fails. or all.
