SOLVED --- No Audio on Acer Aspire One

[wobf58]

I got the Acer Aspire One weeks ago, (Acer Aspire One D255E, Intel N455 CPU, 1GB ram,  160GB HD).  I installed PCLinuxOS KDE 4.6.2 and is working great.  Desktop vesion is working better than Netbook version.  Even with 3d switched on.   The only thing is, the audio is not working.  Any ideas what to do about it?    I just updaded to the newest kernel 2.6.38.3 bfs and all the other software is updated as well

we have 2.6.38.3?!?!?  and i using 2.6.38.2!       

have you verified kmix volume levels?   what channel is the main channel?  could be muted

you can reconfigure sound card by opening pclinuc control center/hardware/sound configuration

i have a toshiba nb 255 with same cpu and probably same board including sound card and i am not experiencing problems, mine is using alsa snd hda intel

Now its working.  I have used snd_hda_intel already but after I have used control center/hardware/sound configuration and I saw that "Enable Pulse Audio" wasn't checked.  So I did that and then it downloaded some missing packages.  That did the trick.  After a reboot it was working.  Thanks for turning me into that direction.  Now I just have to find out how to open ther netbook and upgrade RAM and HD to get an even better performance.  Any help is appreciated.  Thanks again.

i never could get sound with pulseaudio 

our systems must be different

"Now I just have to find out how to open ther netbook and upgrade RAM and HD to get an even better performance"

how much ram do you have?  mine came with 1 gb and kde never uses more than 600 mbs, and that is after a bunch of heavy pages, lots of apps and lots of plasmoids while using compiz, i only would upgrade if i would have to install windows vista or windows 7/8 on this unit but i will only have xp on it(unless someone gives me as a gift a new windows license)

i don't think that you will gain something by upgrading ram unless you see you need it, the only way is monitoring swap and seeing it be used, if you haven't seen swap in use, you don't need more ram

if you still want more ram, be sure to buy ddr2 if the machine comes with ddr2, if it comes with ddr3 buy that, some models doesn't specify what ram you have so avoid buying the wrong module

about hard disk, mine came with 160gb and that leaves 150 gbs for xp and linux(i dualboot that machine too, i need xp for some apps that won't run on wine  and virtualbox doesn't run as nice on this atom), i divided that in 78 for each one(maybe 80 for linux, don't remember)

if you need more storage space, it is possible that you might find more useful a external 500GB or 1TB hard disk that by buying another hard disk

about opening it, if it doesn't have any screws under the unit for each section containing fans, hard disk and ram/wireless card it means that you can detach the keyboard or that your unit can be opened only with the right tool

something like this



and this



i found this video, i hope it is the same model and it can help you(there is other videos but this guy is going slow, something good in my opinion)

(video confirms that you need to remove keyboard to do everything)

also found this post on another forum

Thanks a lot for all your help.  It worked out pretty good.  Since I still need Windows every now and then, like the other day I ordered tickets online and I wasn't able to print them from Linux even my printer was installed and worked on any other task but with Windows wasn't a problem at all.  But since I am also playing around with other distros, I am happy to replace the RAM and HD.

Again, thanks a lot.  By the way, how I close this subject?  I don't saw any buttons for that.

glad to help 

"It worked out pretty good"

so you could follow the video and changed the ram?  good! anything interesting to share?  or all was just as on the video?

"like the other day I ordered tickets online and I wasn't able to print them from Linux even my printer was installed and worked on any other task but with Windows wasn't a problem at all"

i can't help you on that, i don't use printers anymore, printers are evil 

"Since I still need Windows every now and then"

i dualboot on that netbook too, i have xp home, but xp doesn't need much ram the way i use it

"By the way, how I close this subject?  I don't saw any buttons for that."

you can edit the subject of the first post and add the word (SOLVED) so other users can find this post and use the info shared here knowing that a solution was found

there is two buttons on the end of the page, left side, saying remove or lock

remove deletes everything and lock won't let others write any reply to this post

sometimes other users can come and offer better solutions and more useful tips so lock option is not used much here

It was pretty much like the YouTube video showed.  very good explained and not rushed through.  Just like you said.

My Netbook came with Win7 so I keep it on there btu in 95% I am using PCLinux anyway.

By the way.  With 2GB RAM you can upload the live version to the RAM insteasd of keeping it on CD or USBstick.  With 1GB I wasn't able to do that.

thanks again.

win 7 must run very nice on that hardware, yes, i would keep it too!(i hope it is not the starter version, if it is that you can live with it)

i hope you can get and installation disc and wipe/reinstall form clean, the restore disc is not what most users want, a clean start on a netbook changes performance drastically, remove all the extra not useful software added by the manufacturer makes that hardware work as a notebook

"By the way.  With 2GB RAM you can upload the live version to the RAM insteasd of keeping it on CD or USBstick.  With 1GB I wasn't able to do that"

a very good reason to put more ram, you gave me a reason to upgrade ram 

also adding ram and could make more simple to virtualize xp here, it is slow but on 1 gb of ram, xp only can have 512mbs and that is not enough
