Hi, Have quite an old system Pentium 4 2.0 Ghz + 1.5 G of SDRAM memory. Windows XP SP2, Sound card is Sound Blaster 5.1 -cannot at present obtain any sound on YouTube. Plays CD's OK and Radio, BBC sites all OK but clips from YouTube in particular -total silence! Any ideas? Grateful for any tips.
(I know should get something newer and will do soon but would like to fix this-if possible.)
