Well, the audio has stopped working. I tried installing Ekiga last night
but couldn't get the echo test call to work. Ekiga reported that there
was a problem with the audio device. I tried USB headphones as an
alternate audio device, no luck.

At present, I am hearing the clicks after every several seconds on the
speakers (as I mentioned earlier above).

If I go to Settings->System Settings->Multimedia and do a "Test" on the
various devices, the motherboard's audio does produce any sound, but I
can hear the audio if I do it on my headphones.

The motherboard is M4A88TD-V EVO/USB3 with chipset AMD 880G/SB850. Audio
hardware is Realtek ALC892.

The sound was working properly when I had 32 bit Debian Testing
installed till yesterday.

The hardware detected on my systems is:

What am I missing here that the audio, that was working in 32 bit
Testing, is not working in amd64 Testing? Why am I getting those clicks
in the speakers? Have I missed some audio related packages? Or is this a
problem with amd64 Debian itself?

Thanks.

Default audio not working on amd64 (was: thinking of installing amd64 Debian ... )

Hello H.S.,

> Well, the audio has stopped working.

Intel on-board sound devices on my two Debian systems
have failed to work properly for about 3 years now.
None of several "fixes" worked.

> I tried USB headphones as an alternate audio device, no luck.

The Altec Lansing headset with C-Media USB-audio adapter
has always worked. I bought a Syba USB-audio adapter
to allow a VoIP ring on speakers, independent of the
headset. The Syba device also works.

Ekiga worked on one of these systems back in Etch or so.
When Ekiga upgraded from 1 to 2 or 2 to 3 it stopped
working. I tried several "fixes" there also and nothing
was effective. Finally I installed Twinkle and it has
always worked with no difficulties. Twinkle is configured
by simple text files; a valuable feature for me.

Regards, ... Peter E.
