More info That is a question I am now asking myself. I have upgraded another machine running an i5 processor and HD 5700 series card. and now have no sound - and no solution at this stage. It seems there are a few bugs in the latest version. Perhaps I'll wait a while before any further upgrades. Bob
hi
some upgrades mute/disable the sound card so it should be a simple unmute to fix it. got caught by this recently I don't think this is the case - or at least I am unable to find any muting. The card appear to be enabled OK.
I have reported it as a bug to launchpad and their tests also indicated
One thing I am a bit confused about (and I am often very confused ;-) ) and really am not familiar enough in this area to be able to dubug the issue: If I do: cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xfe700000 irq 55 1 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xfe640000 irq 56 It shows me Information about Intel cards, yet I am using a Raedon HD5700 - which does not seem to be included? The full info now on launchpad shows the 5700 card: cat /proc/asound/cards 0 [SB ]: HDA-Intel - HDA ATI SB HDA ATI SB at 0xfe4f4000 irq 16 1 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xfe6e8000 irq 19 ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: alsa-base 1.0.24+dfsg-0ubuntu2 ProcVersionSignature: Ubuntu 3.0.0-12.19-generic 3.0.4 Uname: Linux 3.0.0-12-generic x86_64 NonfreeKernelModules: fglrx AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
