I use a compaq Presario CQ 40 note book. while I was on 8.10, I experienced illegibel sound output.... The welcome drum roll was longer than usual and unclear. I resolved this by just cd to /etc/modprobe.d/alsa-base as root and adding:
options snd-hda-intel model=3stack-dig options snd-hda-intel enable_msi=1 options snd-hda-intel single_cmd=1 On rebooting, the sound became perfectly alright. When I upgraded to 9.04, I noticed there was no sound at all. I tried the same thing as above but it didn't work. Hoever, I keep getting some garbled sound in the head phone, even when no sound is playing. The lspci -v -v out put is as under. Can some one help me with this? 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) Subsystem: Hewlett-Packard Company Device 3607 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin B routed to IRQ 22 Region 0: Memory at 9c800000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel ----- Original Message ---- From: Tom <tomdavie...@yahoo.co.uk> To: gang...@yahoo.com Sent: Saturday, 2 May, 2009 1:04:05 PM Subject: [Bug 354398] Re: Acer Aspire 8920G has inaudible audio by default This bug-report seems to have been hi-jacked by a couple of people with individual problems about this. It seems that the original question has become slightly buried by these and doubtless we can expect a lot more people to jump on this as it seems likely to affect a lot of people. It is, of course, quite legitimate for people to seek help about this issue here - certainly it's better than separate questions and separate bug-reports springing up all over the place. I just hope people can find a work-around!

Status in “alsa-driver” source package in Ubuntu: Won't Fix Status in “linux” source package in Ubuntu: Confirmed Bug description: Binary package hint: alsa-base The chipset is in an Acer Aspire 8920G laptop. But please note that this appears to be a generic chipset with a lot of users experiencing the same problems (and possibly the same solution??) This bug applies to Ubuntu 8.04 (final), 8.10 (final) and 9.04 (beta release). In each case all available updates were applied to the Ubuntu OS release. I am currently using ALSA 1.0.18 (fully updated from Jaunty repositories). Output of lspci -v -v is attached. I tried following the Ubuntu audio faqs (e.g. switching to Pulse Audio) to no effect... Basically I cannot switch on the digital optical SPDIF output or get any analogue sound output!! THIS IS A SERIOUS PROBLEM AS JAUNTY IS STILL BROKEN AND SO MANY PEOPLE ARE AFFECTED!! NB I know the "snd-hda-intel" kernel driver module supports the audio device... It still needs a simple work around however and doesn't work out of the box!! Bob Now surf faster and smarter !
