latest skype (version on Centos 7

Hi all!

I've finally been reduced to having to install Skype on my Linux box.
I resisted for years, but now ended up trying it.

and while the latest RPM installs just fine, it refuses to acknowledge
that I have a microphone!

In fact I have two: 1 in the USB web cam (it finds the cam), the second
in a Plantronics USB headset, which works fine but not with skype.
it is as if it doesn't exist.

So, when I connect to someone I can hear them, see them, and they can
see me, but I'm producing no sound output.

All the web hits I can find for nonfunctional microphone on the web
are for Ubuntu. GAH!

running ldd against the skypeforlinux binary results in a huge list
of shared libraries, including libasound (which is what the ubuntu
messages say is missing).

Anybody got a clue?

Thanks in advance!

Hello Fred,

BTw, there's package update (, maybe try it?

I'm not a skype user myself, so haven't tried it, but as there are many
apps that are in FlatHub, and so directly accessible for CentOs 7 (that
comes with flatpak since 7.4.1708)

Have you tried with that one ?

No, but wouldn't it be the same binaries as MS distributes? (which is
what I have).

I posted a reply to my own message in which I noted that I had later
discovered that it works fine with my old analog mic/headset, but
the USB one may as well not be attached, as Skype acts as if it is
not even there.

Weird-but-frustrating, because my USB webcam works, but skype refuses to
use the mic that is built into the webcam (as well as pretending that
the usb headset doesn't exist). so it appears that skype is ignorant
of USB audio devices. Not sure why that would be, since such things are
"just another" audio device.

There is also nowadays web version of Skype. Not sure if it is
available for all users yet, but at least I can access it in my Fedora
install with Chrome.

I've used it only for chatting, so no idea if it works for calls as
well, but perhaps worth a try?

Hello Fred,

Using the same skype version (and former ones), with various
input/output hardware (not the ones you have), I encounter no issue
here with sound setup (I know this doesn't help, sorry). Are you able
to use the hardware you described, especially the input device, with
other software in this CentOS7, starting with alsamixer?

the Plantronics USB headset works great as both earphones and as a mic.
I use it regularly for videoconferences using various web-based
meeting/conference apps.

whenever I plug in the USB headset I have to use pavucontrol to manage
sound. whenever it is not plugged in, I use the sound app in the upper
menu, which turns out to be mate-volume-control (yes, I use the Mate
desktop, not Gnome). This seems weird, but I've grown used to it.

With skype, the audio settings menu refuses to admit to there being any
such audio device attached to the system.

Subsequent to my posting, I discovered that my ancient analog phone/mic
headset works with skype, so I'm more or less set--except I like the
Plantronics a lot better. it (the analog one, not the USB) has two 1/8
inch phone plugs, one pink, one green. plug 'em into the pink and green
jacks, hack at the sound settings for a while, turn off the speakers
(cause the system won't mute them when the phones are plugged in)
and voila.
