I had sound working until 2 days back and now i can't hear a thing - youtube, mp3/vlc, nothing works. I had the laptop connected to monitor which had inbuilt speaker which doesn't work as well and neither does a headset. I took the machine to a technician and he says he can't find any issue with hardware. He didn't open the laptop, just connected a usb device through which he checked motherboard for any issues, and said everything seems to be working fine and he suspects it's a Linux issue. I've other Linux distros installed in the same machine as well - Mint, Debian etc and i can't get the sound working on any of them. I feel it's a hardware issue.
It's a Lenovo R61 and some of the basic sound commands output is shown below -
aplay -l

Can anyone please suggest if there's any way i can figure out what the issue could be or should i be checking with some other technician.
Thanks.

Either there is a physical hardware mute button or a hardware failure.

Thanks for replying. Sound is not muted, i checked that first thing when it didn't work. I suspect hardware failure too, maybe i should take it to another technician and see if anything can be done about it.
Thanks.

Hi murali,
Just out of curiousity, try unloading all of your sound modules and reload them. Then make sure the cards are all unmuted.
Let me know what happens.

Hi Walter,
Thanks for the input. Sound is working fine now. I took the machine to another technician and all he did was change sound card property to Analog and increased the volume button to max, sound just started working again. He says software upgrade might have disabled sound. Strangely doing this in one Linux made the sound work in all other distros as well. And he charged $20 just to increase the volume button :-(. Guess i can't blame him as well, i should've fiddled with different settings myself.
But a lesson well learnt :-). Will mark the thread solved.
