PostPosted: Fri 14 Jun 2013, 03:37    Post subject:  No sound from headphones  

Hi,
I have both 'Lucid 528.005' and Puppy-related 'Studio4' (which is based on Lucid 520) and there is no sound from the headphones ie. there is no headphone option in the alsamixer configuration window and running the alsawizard does not fix this. (I have also tried to copy-in the /etc/asound.state file and some other relevant alsa/modprobe files from Precise Puppy and then run /etc/init.d/10alsa start and this does enable sound to come from the headphones but both the volume control and the sound from the speakers stop working so it is an unsatisfactory solution)

This lack of headphone sound is not a problem in any of the other puppies that I have (ie. Precise, Slacko, Racy).

Can anyone please suggest how I can fix this? (Incidentally, all of the Puppies that I have are run as 'frugal installs', usually and preferably without 'save' files, and I hope to resolve this on that basis, if possible).
Thanks,
dave

Any chance of posting a screenshot of the Alsa screen (with all sliders up at max) - from both a good and bad puppy?

If your sound card is a Realtek ALC269 (or something similar), you'll need a newer kernel, which means a newer Puppy. The fix required to make headphones work on this card was introduced in kernel 2.6.35.7, as far as I remember.

I have an Eee PC 1001PX (a mid-2011 model) - I had this problem for some time.

Thanks for the replies so far.
I took the requested screenshots then found out that images can only be linked to this site via a "publicly accessible web server", something that I am not subscribed to !! So no images I'm afraid.
I forgot to mention in the first post that I have also tried adding the lines:
'options snd_hda_intel model=auto'
'options snd_hda_intel model=generic'
'options snd_hda_intel model=asus'
to /etc/modprobe.d/alsa.conf
and /etc/modprobe.d/alsa-base.conf
and /etc/modprobe.conf
but this has also failed to resolve the problem.
As for Lucid 528.005 (with no headphone sound) the soundcard is Hda Intel with a Realtek ALC259 Chip.
EDIT 1: The kernel for Lucid528.005 is 2.6.33.2
EDIT 2: The kernel for Studio4 is 2.6.33.5 - rt25
EDIT 3: As for Precise 5.5 (with headphone sound) the chip is Realtek ALC269 and the kernel is 3.2.29 so Iguleder is no doubt correct to point to the kernel as the cause of the problem
I'm not too troubled about the problem as regards Lucid528.005 but as you can imagine the sound issue is crucial with puppy-related "Studio 4" in which the same problem arises as that with Lucid. What is puzzling me is that I only downloaded the latest version of Studio 4 last week (it seems to have been released in December 2012?) so I would have expected no sound problems with it at all but, at the moment, the lack of headphone sound is proving to be a bit of a problem.
EDIT 4: For the record, I am using an Asus netbook Eeepc 1011PX.
Thanks
dave

Studio is a remastered Lucid, so they use the same kernel. Despite of its 2012 release date, technologically, it's dated back to 2010.

EDIT: yes, you have the problem I had with the 1001PX.

EDIT 2: forgot to mention, Lucid is no longer developed, so there won't be a version with this fix (e.g a newer kernel).

Thanks, Iguleder, for the latest info.
I have edited my previous post simply to correct and to try to clarify a few points for the benefit of anyone else who comes across this issue.
You are no doubt correct to identify the old kernel as the source of the problem.
I don't know whether I'll be able to do anything about it as regards Studio4 but I'll look into it now that I know what the problem is. Now re-posted on Puppy Derivatives forum, see:

Thanks again.

While the Studio 4 kernel is outdated now, it isn't the same as in Lucid. Studio 4 uses a 2.6.33.5-rt25 kernel.

Davec, you can post the screenshots directly to the forum as long as they are small enough. The forum won't display images larger than 800 pixels wide. Take the screenshot, then use Graphic -> mtPaint to crop and then reduce its size so the forum will show it. Save the image as a jpeg (because that usually gives the smallest file) and then include it in your post by clicking on the Browse button beneath the forum's compose window.

Now, about posting the same question several places in the forum.... Mad

Thanks for your advice about images.
I re-directed my original post to one other location (not "several places") simply because I subsequently realised after posting it that the 'puppy derivatives' forum seemed better equipped than the 'beginners forum' to be able to resolve the problem specifically in so far as it relates to (puppy derivative) Studio4's more 'specialist' kernel. (ie. I wasn't intending to clog-up the forum unnecessarily or create work for anyone or anything like that !!).

Hi davec60,

Here's a third place for you to consider.
It is aptly called 'Audio' and seems to be the best place to post your issue.
