I’ve been gifted a Dell Latitude D520 which had XP Pro on it - now removed and replaced with Zorin O/S. All seems ok with the installation except I can’t get sound from the onboard speakers. Plugging in external speakers works ok - I don’t have headphones available to test but assume they would work, as the jack socket is ‘live’.
Looking online, there seems to have been sound issues with this particular model of lappy right from the off. I’ve tried a few things but nothing will restore sound. Any ideas?
It looks now like this is a hardware problem rather than software. The Pulseaudio control shows audio is configured correctly and the volume control output Alsa plugin bar is moving with radio broadcast. This does not change when the external speaker plug is removed - i.e. the bar still moves but no sound from the onboard speakers.
Searching this model on the Web (Dell Latitude D520), there are hundreds of posts in the same vein, with as many solutions! A strong candidate is the headphone socket which has an internal switch that toggles between onboard speakers and headphones when the plug is removed. This switch may become stuck, which has resulted in Dell replacing part or all of the motherboard in the past. Erm… I think this one might be out of warranty!! ;D
Worst-case scenario is I buy a set of lappy headphones, otherwise I plug in to my PC screen jack and use the in-built speakers there. Rather defeats the object though… :
I’m half-way there, so to speak, so many thanks for your advice thus far… I’ll keep trying and post the outcome if I ever get that far!
Just a thought - would there be a way of disabling said switch? I’d have no probs with losing the headphone facility if the onboards were working…
Alsamixer looks ok to me - nothing related to headphones.
F3 shows Master at 100, PCM at 100 (but no box at the bottom where it can be muted/unmuted), then S/PDIF and S/PDIF Default PCM both at 00, but with no upper slider. Mute/Unmute on Master channel works properly.
