AFAIK, microphone bad quality is more related to the hardware, not
the software. My onboard "Intel high definition" sound chipset (ICH7
compatible - Intel 945GNT) has a bad output sound, but a much worse
input (microphone). I have tried using Windows XP, CentOS, Ubuntu,
many softphones (Skype, X-Lite, Ekiga, Twinkle) and definitely the
problem is hardware (or all drivers are broken).
the output quality of the Intel branded motherboards I've used has
been quite good. Microphone inputs somewhat less so, but still
plenty good enough for telephony IF your microphone has high enough
gain. If someone is recording high fidelity (music, etc) from
microphones, I recommend they get an external microphone preamp and
use the line input on their sound card, or even better a USB
input/output box.
for voice/telephony, USB headsets are the way to go.
I also have one trust USB headset and it works, except the volume
cannot be adjusted, it's always max (and that's not nice for a
headset...).
I have 20 desktops running FC4/Centos44 on AMD based Motherboards. The
sound is onboard using a Nvidia chipset. Using skype and esd/arts the
sound is very good, no problem. As soon as I try any of the softphones
the mic is heavily distorted. I can even hear a hum as if the ground
shielding is not properly connected. Since skype works so nice (using
eithers OSS or alsa) I expect this to be a software based problem not
hardware. And one softphone is working with FC4 (slfphone) but not on
Centos4.4. The mic sound is less compared to skype (there is a hiss,
when pronouncing the letter 's' the sound is distorted) but upto now
that's the only one that is acceptable for only FC4, not Centos :-(
Well I tried Twinkle and it works, but on a scale from 0 to 10 I give
the sound a 5 were I can give the Skype sound quality a 9+. Strange that
it seems to be so difficult to get good sound quality on Centos/FC. My
motherboards are A8N32-SLI Deluxe and Foxconn NF4UK8AA-8EKRS both
equipped with onboard Realtek ALC 850.
Has anyone experience (good or bad) with the Realtek ALC 850?
