Hello everybody,
I have spent a lot of time trying to solve these problems, without luck, so i am here asking for help.
The starting point was how to get skype working on kubuntu dapper amd64: I have read about several ways to do this, and I have tried almost all of them, but audio problems are still here. That is:
- first I tried to install it from the .deb package available on skype web page
(skype_1.2.0.18-2_i386.deb) with dpkg -i -force-all. The package has been installed without problems; I have read that to avoid sound problems, it should be launched using artsdsp -m, but I get this error:
ERROR: ld.so: object '/usr/lib/libartsdsp.so.0' from LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object '/usr/lib/libartsc.so.0' from LD_PRELOAD cannot be preloaded: ignored.
that seems to refer to some incompatibility in libraries.
However skype starts, but when I try to test the sound calling echo123 I can hear no sound. If i try without artsdsp -m the result is the same.
(Question: is artsdsp -m really needed? Isn't enough to set 'auto suspend if idle' in system settings -> Sound&Multimedia to a very small (say 5 seconds) period of time ?)
I have tried then to install the .deb in the dapper i386 chroot I have, but again using both
dchroot -c mychroot -d 'artsdsp -m skype'
and
dchroot -c mychroot -d skype
I have no sound, even if the error message reported above about preloading of libraries has obviously disappeared.
(Question: I have also tried to mix artsdsp from 64bit environment with skype from 32bit one, using
artsdsp -m 'dchroot -c mychroot -d skype'
but I get an error message saying "artsdsp works only for binaries"; is there any way to have this working?)
So I started to think there could be some general problems with audio settings in my laptop (an Acer Aspire 5024, Turion ML-34 based). But I have sound working in other apps (say Amarok);
here's
what lspci -v says about my audio card:
0000:00:14.5 Multimedia audio controller: ATI Technologies Inc IXP SB400 AC'97 Audio Controller (rev 02)

And all relevant modules seem to be loaded, according to sudo lsmod|grep snd:

(btw, I am using kernel 2.6.15-23-amd64-k8)
I have checked kmix settings, and everything seems ok there; but I have noticed that if i try to record any sound using krec I have no success.
Also here's what aplay -l shows:
**** List of PLAYBACK Hardware Devices ****
card 0: IXP [ATI IXP], device 0: ATI IXP AC97 [ATI IXP AC97]

Subdevice #0: subdevice #0

and also arecord:

Subdevice #0: subdevice #0

I can play sounds with aplay, but I cannot record anything with arecord, even if I try several differen input sources in kmix
Any help will be appreciated.
