Arch 64b/KDE 4.5.2- No sound after Skype installation

mibadt · 2010-10-18 10:28:31

Hi,
I've a fully updated Arch 64b/ KDE 4.5.2 system.
Initially, sound worked fine till I installed, from repositories Skype (and needed 32b libraries).
Afterwards, every time the system boots and I log in (in KDE), I do not hear KDE's sounds and get the following error:

"Removed Sound Device:
KDE detected that one or more internal sound devices were removed.
Do you want KDE to permanently forget about these devices?
This is the list of devices KDE thinks can be removed:
Output: HD-Audio Generic, ATI HDMI (HDMI Audio Output)"

Needless to say, Skype doesn't work either, at least the speakers, although I can hear myself knocking on the Mic through the speakers. Skpe's option provide local Pulse Audio server as the sole audio device both for input and output.

My new hardware consists of a Gigabyte GA-890FXA-UD5 (ver 2.0) MoBO, with an on board Realtek ALC889 audio codec, and an HDMI complient PCIe graphic card (Radeon 5670). My speakers are connected to the rear audio ports of the MoBo (currently I don't use the HDMI audio capability).

I've searched the ALSA Wiki and added some relevant outputs-Sorry for the long input below!

Both alsa-utils and alsa-oss are installed.

Running alsamixer I initially get Pulse Audio card at 90% for Master (Only channel displayed). Selecting the sound card (F6) provides 2 options (besides the default): HDA ATI SB and HD-Audio Generic.
Selecting the HDA option I get all Realtek channels at 75-100% level with only the S/PIDF muted.
Selecting HD-Audio generic selects the graphic card and displays only S/PIDF @ zero.

Is my problem related to the fact that lspci (see below) does NOT list the 889 module, and instead I see an Intel?? module?

Please advise!

Thanks!

I had problems before with KDE also asking me about forgetting a device. I believe what happened in my case was that when the system booted up, the order of the sound cards (card0, card1, etc; as listed in `aplay -l`) kept changing. So for example, one time it would boot up and KDE would use the mobo's sound (which i want it to), and on the next bootup, the system would think my webcam was card0, so KDE would try and use the webcam for sound output rather than the mobo.

I fixed the issue by setting the order of sound cards as done here: http://wiki.archlinux.org/index.php/Als … sound_card

Hope this helps

Thanks for the link!
I'll study it.
