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 http://paste.pocoo.org/show/461744/ 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, der Max
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. Dale :-) :-)
