Hi folks. Approximately a month ago I began having audio problems on my HP-15 laptop. I discovered the problem when listening to music videos in youtube. The problem is random and goes from a mild stutter to a greater stutter / "interference" type sound. It also does this with the few .mp3 files I have. It also does it in instructional videos where a human speaks. My laptop is split between Windows 10 and Kubuntu 14.04. This does not happen on the Windows 10 side. I'm so ignorant of Linux that it's embarrassing. Any questions asked of me will likely require a little patience. A member on the Kubuntu forum had me pull this data from the Terminal for his scrutiny. He hasn't replied back. Perhaps it'll be of help.

It won't hurt to get some diagnostics until some help comes along.  If you want please post the outcome of these commands.  I have a few ideas for you.

sudo aplay -l

and

lspci -v | grep -A7 -i "audio"

I have nothing to support this. As stated, this just began happening out of the blue weeks ago. There are tons of updates, 2,3,4 times a week to include "security", "software", and others. Just wondering if an update is the cause.

I don't think I can help any further, maybe someone will come along soon.

 

I does look like you have an extra device there, do you use the HDMI sound output setting for an external device like a tv?  Perhaps that needs to be turned off unless it is being used.

 

good night

Thanks for your help. Regarding HDMI, I have no idea. If so, it happened without my knowledge. Thanks again.

I opened VLC from Terminal. Opened a mp3 to check for any errors displayed in Terminal. The last two entries are from exiting VLC.

Sorry bamashooter, I have very little experience with Audio.  I did see one person with the same problems as you, and they went into the BIOS and Enabled Audio.  Don't know if that will help but it's worth a try.  Perhaps something got changed in BIOS without your knowledge, like a firmware update via the Windows side, I think this is possible via OEM Update Software like HP.

 

This part is interesting though, in my searches and on my pc only has one entry for sudo aplay -l and no HDMI entry like yours.

Thanks. I ran alsamixer in Terminal. Is this of any diagnostic value?

Try this first.  

 

I always start with the simple stuff first, no need to move to more complex stuff yet.  I will look at my Kubuntu settings after you try this, that's what I would do.

 

I will look at my alsamixer also soon, been in Windows a lot lately.

 

Before you get help with advanced fixes, do you have a backup plan?  Are you using Timeshift, rsync or any other backup devices to copy your root system.  And is all you personal data backed up?  If you have a lot of time invested in this install we should cover this before any files are altered, which may or may not be necessary.

Maybe this will help, clearly the settings are different and I think that is the issue.  I chose F6 and you can see those options in the little blue dialogue box in the middle.  Make sure to write down any changes you make.  There are many other Sound settings but don't know if any would help.  PulseAudio and Audio and Video Settings in KDE would be the other two

If I tap F6, which is also my audio on/off key, I get no window. It only powers on/off the audio. On a few of the colored bars, it changes "MM" to "00" which appears to be taking it from mute to on.

Going by what you're saying, I take it that this problem started occurring one day, and before that Kubuntu's audio worked fine? Is that correct?

Have you tried booting your computer with a Kubuntu ISO to see if it has the same problem?

I never noticed the problem til weeks ago. I doubt had it been happening that I would have missed it. Moments ago, I hooked my older stand alone hard drive to the laptop. It has mostly music on it. I played for songs from it and had no issues. I just now played 2 songs that are on my laptop (Kubuntu) hard drive. No issues. What??? I just played a song directly from youtube with no issues. What the crap? The only 2 differences are (1), the external hard drive is plugged in to the laptop, (2), this morning I had a small "software" update downloaded which I installed. My external HDD has 281 gb free so I'm gonna backup my Kubuntu to it. I have a "please tech me how to backup Kubuntu" thread going in the Kubuntu forum. Reckon I should leave well enough alone for the moment?

Yep, started a few weeks ago to the best of my knowledge. Haven't tried booting to iso.

Cool. Looks like the issue is resolved. :)
