This problem is in http://bugzilla.kernel.org/show_bug.cgi?id=10941

I found a solution.

[sleipner (andreas-zieritz)]

I don't know if this is the same bug, but the internal microphone does not work on my Acer Travelmate 8100 either.

[Thommyboyothagreen (thommyboyothagreen)]

Same with my Acer Extensa 5420.

[nicky.7 (nickkkk7)]

Same with acer 5175z. If you need more report let me know

[Amit Kucheria (amitk)]

Unfortunately it seems this bug is still an issue. Can you confirm this issue exists with the most recent Jaunty Jackalope 9.04 release - http://www.ubuntu.com/news/ubuntu-9.04-desktop . Please let us know your results. Thanks.

[Gianfilippo (press-nalug)]

I can confirm internal microphone for Acer Aspire 5720 not working on Ubuntu 9.04 with latest upgrades.

[Mika H. (mikak3)]

Any idea how to fix this in Ubuntu 9.04????? Beacuse I have TravelMate 7520G and my microphone doesn't work.... :(

[gidantribal (aedo999)]

Same for aspire 6920G

[Eric Miao (eric.y.miao)]

The fix mentioned has been incorporated in mainline kernel since v2.6.29.

If you could also test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine this issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[Leann Ogasawara (leannogasawara)]

Marking this Fix Released for Karmic 9.10 since it will target the 2.6.31 kernel and has most recently be rebased with the 2.6.31-rc2 upstream kernel. Images are currently available for testing - http://cdimage.ubuntu.com/daily-live/current/ . Thanks.

[gidantribal (aedo999)]

is it fixed also for 6920G?

[James Ravenscroft (ravenscroftj)]

Unfortunately, Leann, this is still an issue for me on my Acer Aspire 6930G running karmic 64-bit even with kernel 2.6.31rc6 installed.

[gidantribal (aedo999)]

uhm... same problem here too. I also bought an external mic, but this issue
is painful when you can't keep everything with you (external mics
included), e.g. in conferences...

I think, dear Jam, we have to wait for long, since it's a well known bug and
there's no sign of interest in fixing it.

and this for BASS (tuba), which is definitely a secondary problem BTW:

[Orcodrilo (orcodrilo)]

hello, my Acer Aspire 5810TZ has no knowledge whatsoever of having a built in microphone, I am a baby ubuntu user, so if anyone knows of some software that fix this It would be greately appreciated.

[Malcolm Gilbert (me-gilbert456)]

I have an Acer TravelMate 5730. I am using Ubuntu 9.10 but cannot record sound from either an external microphone or the internal microphone, all I hear is static. I have tried recording in the 'Sound Recorder' and also in 'Cheese'. As a Linux newbie I would like to be informed of a simple resolution to this issue. I really do not want to regress to Windows 7!

[Konstantinos Togias (ktogias)]

I have the same problem with a clean install of ubuntu 9.10 on an Acer Aspire 6530G Laptop. I attach lshw output

[lyndon (lghood)]

Added self as affected - Ubuntu 9.10 on Acer TravelMate 8100. Internal audio appears in System Prefences/Sound/Hardware (analog stereo duplex) but the levels indicator, and Sound Recorder, only show even noise. Some success with external USB webcam mike.

[JoCo (jcody10)]

Similar issue - using a Gateway Lt2005U (Acer is mother company of Gateway)
External Mic works fine
Internal Mic does not work well - if I adjust sound settings to amplify @ 100% and then record I can get something @ low quality.
I'm not a developer/expert by anymeans - but please let me know if theres any other info I can provide to help with this.

[LordMoregore (aekengren)]

Same issue here. I'm running Ubuntu 9.10 on my Acer Aspire 5536 and I can't get my internal or external video/mic working.

[Long Le (lelong88)]

same issue with Acer Aspire 5100. a few months ago at least the mic was still in sound preference even though it didn't work. after some updates i'm not sure which, it completely disappeared.

[lisar915 (theurbangrind)]

Same here. I'm using a Vaio PCG-K33 laptop. I would love to know of a fix.

[Shane H (shane.h)]

I might or might not have the same bug. If I don't, please PM me so I can set up a new bug.

I have an Acer Aspire 5551. The internal microphone doesn't work in Ubuntu Natty 11.04, but does in Windows 7.

[Seth Forshee (sforshee)]

Shane: Please open a new bug.
