[Alsa-user] PinkFaun C-Media CMI8888 problems only on Intel i7-i5-i3

2017-06-07 Thread AudoLinux 
I have a PinkFaun I2S card.  This one is using C-media CMI and the 
only output is I2S. What is strange is that this card is working fine 
only on AMD processors (or Intel Atom) but not , for example, on Intel 
i7-6700. In this last case there is a very high, noisy and distorted 
sound at 192kHz. At lower sampling rates, for example 44.1, the sound is 
better, but there are periodic noises.
I have disabled embedded audio in BIOS, have checked with hda-analyzer, 
I have confronted the loaded modules with a working system (the modules 
are the same), I have increased the buffer, I have checked with 
standard, realtime and ck kernel, tried to disable c-media specific 
driver and a lot of other things, without results. My system is 
archlinux updated to the very last kernel and Alsa version.


What is more strange is that, if I boot from wtfplay minimal 
distribution, the card is working!


I hope some people can give me some suggestions, because I have tried 
everything!

Paul, this sounds like hardware to me.  I would try another set of
headphones or a different connecting cable.  I would try the same
headphones into the speaker output of the desktop and see what the
behaviour is.  I would try the speakers into the headphone output.  And
finally I would try a live USB stick or CD with a different distro /
different kernel.

Paul,
Do the headphones have a TRRS (4-conductor) plug?
Many do these days, as they are designed for mobile phones.
You may need a converter from TRRS (tip-ring-ring-sleeve) to TRS 
(tip-ring-sleeve).
Some manufacturers are not forthcoming with information about the wiring 
of their plugs, but it's usually reasonably easy to discover by measurement.
There are, of course, several "standards".
A search on the CTIA vs OMTP standards may prove informative.

Worth checking before software.
If the software differences are absolutely repeatable, then I defer to your 
results.

Hope this helps
John Mills

Different kernel versions?

[Alsa-user] Problem with front headphone connector

2017-06-07 Thread Paul Menzel 

Dear ALSA users,


Linux 4.9.30 is used.

Using a Fujitsu Desktop ESPRIMO P756 E85 with a Realtek ALC671, 
depending on the file with stereo sound, I need to pull the headphone 
jack a little out to hear both channels. But for others, I need to push 
it back in.

Do you know if that is a hardware defect, or can some workaround be 
added to the Linux kernel?



Kind regards,

Paul

Yes, most probably.  I have contacted the developer and he reported that 
"...I went quickly through my emails and discovered, that one user was 
asking me about CM based device. His problem was that he was getting 
a noise when he was using 'aplay' utility. With 'wtfplay' he was able to 
play audio correctly..."


However the tests with AMD v/s Intel have been made with the same linux 
arch image on a number of computers, nothing different. I am finding it 
difficult to find a reason!
