Hi, I have an issue here which I don't believe is Fedora related but I just want to make sure and thought I'd ask anyway in case someone has an idea what's going on. I currently have an Intel DQ35JO motherboard in an Antec P182 case. I bought this motherboard a while ago since I had to RMA the ASUS P5B-VM Do motherboard I had before and I didn't want to be without a computer for weeks. So tonight I was watching some videos and it was getting late so I thought I'd put on my headphones but instead of just plugging them in the jack on my speakers I thought I'd try the front panel on my case since I couldn't remember if I ever tried them. So anyway I plugged the headphone in and the computer turned off... I unplugged them and restarted the computer and now there's no sound at all. So anyway I started looking around, in the sound card detection it does find the onboard audio but there's nothing listed in the PCM device. I also had the same audio issues with the ASUS I had previously but I don't remember if I tried the front audio with that one or what happened that the sound just stopped working... Here's the output of lspci -v which shows that it finds the sound card: 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02) Subsystem: Intel Corporation Unknown device 0012 Flags: fast devsel, IRQ 22 Memory at 98420000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Kernel modules: snd-hda-intel And lsmod shows the module is loaded: snd_hda_intel 274529 0 So what I'm wondering is, is there something wrong with the front panel connector of the case that could have shorted out the onboard sound card on both my motherboards? Anyway that's what I'm wondering but I'd like a second opinion... I'll probably send an email to Antec tomorrow to see what they have to say about it... -- Jean-Rene Cormier <jrc@xxxxxxxxxxxxx>
