THINKPAD X1 EXTREME G1 // HEADPHONE JACK CRACKLING NOISE HORROR // DEAR LENOVO!!!

2019-01-22, 1:36 AM

 

Dear Lenovo,

 

when are you finally going to officially address the fact that many recently released notebooks suffer from audio issues when listening to audio via the headphone jack. In specific, the phenomenon can be observed best when listening to audio via headphones. If you listen to audio which quickly changes the volume then you can hear a clear crackling noise on the right audio channel. If you listen to normal speech for example, which includes small breaks you can hear a crackling noise each time before the person starts to speak and when the person stops to speak. A good example for observing this issue is the following YouTube video:


https://www.youtube.com/watch?v=XCOHTLNMvCE

 

Listening to the first two minutes of the video linked above with headphones plugged into the audio jack is already enough to observe the issue. If your device is affected you will be able to observe a little crackling noise on your right headphone audio channel, each time there is a small break between the talking. This issue has already been reported a thousand times all over the internet and not only affects the ThinkPad X1 Extreme, but also many other high-profile ThinkPad product lines.

 

For example, this issue has been mentioned in the official Lenovo forum here, but you chose to not respond. Instead you let people struggle with this issue. Moreover, the forum entry below confirms that also the ThinkPad P1 is affected and that there is no reliable solution to fix this issue permanently:

 

https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Extreme-Audio-Popping/td-p/4206570

 

The issue has also been reported in the next forum entry below, but the suggestions there do not fix the issue:


https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/ThinkPad-X1-Extreme-suffering-from-crackling-sounds/td-p/4276292

 

In addition, a similar issue with the notebook speakers has been reported here in the next forum entry mentioned below, but you do not provide a clear statement. In fact, the entry below shows that not only the ThinkPad X1 Extreme is affected by audio issues, but also the ThinkPad P52s. It also shows that you did not made any effort to inform the X1 Extreme owners that there might be an issue with the X1 Extreme even though you investigated some speaker issue:


https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile/P52s-After-Newest-Power-Mgmt-Driver-Speakers-Make-Popping-Noise/td-p/4189321

 

 I hope you can also start to officially investigate the ThinkPad X1 Extreme headphone jack issue. On top of this, the issue with the ThinkPad X1 Extreme audio has also been reported on reddit many times, since people are obviously already getting desperate of your unresponsiveness and your horrible support, which only suggest to exchange the headphones. Are you serious Lenovo? So, what you are trying to tell me is that all the headphones in the world are broken? I tried four different headphone pairs myself all with the same annoying issue and so did many other customers. I also switched and uninstalled the drivers one million times, which of course did not help anything.


The entry below shows not only another case of the ThinkPad X1 Extreme but also that the ThinkPad X1 Yoga Generation 3 is among the affected devices:


https://www.reddit.com/r/thinkpad/comments/9xshly/the_dreaded_audio_pop_on_the_x1_extreme/

 

Here is another case of this audio issue regarding the X1 Extreme. The solution in the entry below does not solve the crackling noise for listening to audio via the headphone jack:

 

https://www.reddit.com/r/thinkpad/comments/a8k2q1/audio_crackingpopping_fix_realtek_generic_audio/

 

The next three reddit entries below show that also the T480s might be affected as well as the X1 Carbon Generation 6:

https://www.reddit.com/r/thinkpad/comments/9zlz6m/t480s_headphone_jack_popping_noise/

 

Last but not least the most important information in order to get closer to the cause for all this mess. The entry below shows what might be the source of the issue and most importantly shows that IT CAN BE FIXED on Linux. It also highlights that the CODEC ALC285 might be the source of all issues.

https://github.com/torvalds/linux/commit/c4cfcf6f4297c9256b53790bacbbbd6901fef468#diff-6cb60ab78549a5b6838f746b9e128105

 

ALSA: hda/realtek - fix the pop noise on headphone for Lenovo laptops

 

We have several Lenovo laptops with the codec alc285, when playing

sound via headphone, we can hear click/pop noise in the headphone,

if we let the headphone share the DAC of NID 0x2 with the speaker,

the noise disappears.

 

The Lenovo laptops here include P52, P72, X1 yoga2 and X1 carbon.

 

I have tried to set preferred_dacs and override_conn, but neither of

them worked. Thanks for Kailang, he told me to invalidate the NID 0x3

through override_wcaps.

In addition, the link below shows, given the information is accurate, that you Lenovo are not completely unaware of this disaster:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1805079

[Impact]

Lenovo told us that some linux uers reported headphone noise on Lenovo's

website. After investigating, we found those Lenovo laptop models all

have the codec of alc285, and we can reproduce the noise problem too.

 

[Fix]

Don't use the DAC of headphone, let headphone share the DAC with speaker,

the noise disappears.

 

[Test Case]

After applying this patch, we tested on Lenovo P52, P72, X1 carbon and X1

Yoga 2, no noise anymore


Obviously, this issue affects also windows systems, so how about you finally get your things together Lenovo and fix this intolerable situation. We are in the year 2019 and I bought a 3000 USD notebook, I think I can at least expect that I can listen flawlessly to my music over headphones without programming my own operating system first. Tell me, is this too much to ask? And tell me what you are going to do now ?

Suggest editing the title of the thread to include the other laptop models so that others can vote up this thread.  P52 has the same problem for sure.

New Realtek audio driver version 6.0.1.8619 fixes this problem for the P52.

I have a brand new X1 Carbon 7th Gen, bought in December of 2019. I have this exact issue and none of the fixes have worked. How can this still be an issue, Lenovo? the official support doesn't even answer.

Also have the same issue on X1 7th Gen, now in April 2020.

 

No solution yet found, and very disappointed on such a premium product.   Really bad timing given amount of video conferencing with headphones at present.
