Hi all: I've newly bought a laptop (details at end) & installed Jessie 8.2. All's well except that I have no sound. I've done quite a lot of online research but got nowhere. I'm looking for ANY other practical ideas, please.
What I've done: 1. Checked alsamixer & pavucontrol - I can't find anything muted. alsamixer shows 'Speakers' as muted at the start of each session. Increasing the volume on 'Speakers' (third from left) makes no difference. The only sound I have achieved at all is when (using alsamixer) I raise the levels of 'Mic Boost' high, when I get 'white noise'. This, however, suggests to me that the speakers are functional. I even tried these: 'The Steve Litt Diagnostic Tools' from http://www.troubleshooters.com/linux/sound/downloads/ unmute_all.sh just hangs after printing its headphones warning. 2. Checked drivers / kernel modules. These seem to me to be a. correct & b. working. pavumeter shows appropriately fluctuating signal levels when I play a track through aplay or through vlc. 3. Torn my hair / crossed my fingers / lost sleep / read a lot - much of it outdated (I wish people would date online troubleshooting guides etc BEFORE, near the end, it suggests I add (e.g.) etch-backports to sources.list). I've provided all the relevant information I can think of below - of course I'd be happy to provide anything else that would help. If anyone has any ideas, please let me know :) I follow the linux.debian.user usenet group on pan regularly, but do not otherwise receive e-mails. You're welcome to e-mail me with any suggestions.
