Hello all,
I recently bought a Zotac Barebone ZBOX HD-AD02 AMD E-350 and installed
Gentoo on it, what is working more or less very well except the sound. I
did everything according to gentoo and gentoowiki docs, I installed (due
to laziness) a gentoo-sources kernel with genkernel and Sabayon linux
standard configuration, and I am using pulseaudio, but when I launch
firefox or chromium from console and play some sounds, I get lots of
these error messages:
"ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave"
I already googled for it but didn't find something helpful. The Zbox has
a HDMI and a standard device:
# lspci -v | grep -i audio
00:01.1 Audio device: ATI Technologies Inc Device 1314
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev
40)
# cat /proc/asound/cards
0 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at
0xfeb44000 irq 40
1 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xfeb40000
irq 16
You can find the complete alsa-info output at

For me, the interesting part is this section:
**** List of PLAYBACK Hardware Devices ****
card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: SB [HDA ATI SB], device 0: ALC892 Analog [ALC892 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: SB [HDA ATI SB], device 1: ALC892 Digital [ALC892 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
Is is possible that ff and chromium are sending data to HDMI since it is
card 0? If you think, it would be helpful to disable card 0 or change
the order, please tell me how to do it?
I highly appreciate all kinds of help!
Kind regards,

A silly question for a common problem. You did unmute the volume
right? The default is to have everything muted so it is very common for
folks to forget that little but important detail.
Also, on one of my rigs, I had to unmute with both Kimix and alsamixer.
Just a thought. I've done this myself.
and don't forget to mute spdif optical raw
and try without pulseaudio first.

Hi Dale and Volker,
I tried it without pulseaudio first and, Dale, my card is unmuted. ;)
Totem and vlc are working without any problems but ff and chromium
aren't able to produce sound - and it is somehow related to the error
message above.
But Volker, I highly appreciate the tip with the spdif and I'll try that.
Thank you very much.
Kind regards,
Max
