Dear all, |
2 |
|
3 |
It's been quite a while since I noticed this annoying behaviour, but I |
4 |
could not find any information what might cause this. So the problem is |
5 |
that at lower volumes my HD-Audio with Conexant becomes very noisy and |
6 |
this is regardless of the sound system or speakers/headphones I use. |
7 |
|
8 |
The noise can be described, as high pitched, sandy texture noise |
9 |
heard during more expressive parts of the music or speech. |
10 |
|
11 |
I experience this on two Thinkpads (x200s and x200) and it very evident |
12 |
when I connected external speakers, they produced a lot of this noise, |
13 |
or maybe I just could hear it better, because of the frequency response |
14 |
of the speakers. |
15 |
|
16 |
Does anybody have some similar issues? |
17 |
|
18 |
My current audio setup: |
19 |
|
20 |
* PulseAudio (but the problem is experienced with ALSA as well) |
21 |
* MPD for music playing |
22 |
* Conexant and other related modules compiled in, power-saving |
23 |
features enabled. |
24 |
|
25 |
What I have tried to eliminate the noise: |
26 |
|
27 |
* Various levels of Master,PCM,Headphone channels via Alsamixer |
28 |
* Increase the sample rate in MPD settings. |
29 |
|
30 |
The noise can be clearly head when I Have the following setting on my |
31 |
Alsamixer: |
32 |
|
33 |
* Master ~50 |
34 |
* PCM 100 |
35 |
* Headphone 100 |
36 |
|
37 |
Does anybody has any thoughts on why am I experiencing this? |

Thanks a lot, |
