[SOLVED] Sound quality from correct to awful depending on output/media
Hi everyone, this is my first post, so please notify me if I'm doing anything that is not of you liking (I read the newbie posts).
I recently switch completely from ubuntu to Arch on my mabook air (mid 2011, 11").
I cannot get the sound to work properly and spent a lot of time trying different solution out there without success.
Being not very good with everything around driver I think I now require the help of the community :-)
The issue :
- I have alsa and pulseaudio installed
- Speakers works fine
- My headphones (they include a microphone) work fine but I noticed it was somehow unstable (noise)
- My Yamaha THR10 amp sounds awful on the same output as the headphones. I can barely hear the music playing behind the noise.
- The Yamaha works fine with my smartphone.
- I tried different sources and formats.
- My system is up to date.
- I noticed several module starting by snd_hda* are loaded but I have no idea if it's a good thing or not
- I removed all the tests I did in /etc/modprobe.d/ to start from scratch. (see lsmod below)
- I remember having some noise on ubuntu on unstable sound
- I have no way to try the output with a different system but I will try to do that soon

Edit: I just noticed that when I unppluged the external output (that is now not playing the music at all, just small noise) I have a suddenly higher sound on the speakers before the sound comes back to them normally.

Additionnal info: some sounds play well on my headphones, but others have a lot of noise while they play perfectly on speakers

Re: [SOLVED] Sound quality from correct to awful depending on output/media
I was able to plug the THR10 in USB as a sound card and it works perfectly find so it seems to be related to the macbook's sound card's driver.

Re: [SOLVED] Sound quality from correct to awful depending on output/media
Well, I was deperate and tried random values for card model as I couldn't find the documentation, and this fixed it…
$ vi /etc/modprobe.d/sound.conf
# specify card model to avoid headphone distortion on macbook air mid 2011 (snd-hda-intel C200)
options snd-hda-intel model=intel-mac-auto
