For the sake of completeness, I provide a new alsa-info.sh output: http://sprunge.us/ZWLF (I blacklisted the snd_hda_intel this time just to be on the safe side). The git-link below ( http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=src/conf/cards/NFORCE.conf;hb=HEAD ) seems to point to the .conf for nForce2/3; min is a nForce4 (don't know if nForce4 is supposed to use this same .conf). THNX already, Bye! _____ *Gilles Hemberg* /gilles.hemberg@gmail.com/ On 03/10/2014 09:31, Raymond Yau wrote:> > > > Sorry to bump in like this, but I was advised to submit a bug-report > for the ALSA-drivers on my HTPC: no sound comes through out of my AVR > when I select the digital output through SPDIF (TOSLINK). > > > > The relevant parts of my HTPC are as follows: > > * CPU: Athlon64 X2 3800+ > > * Motherboard: ASUS A8N-SLI Deluxe motherboard (BIOS 1805) > NForce4 with CK804 sound (relying on a Realtek ALC850 chip) > > > * RAM: 2x 512 MB DDR-400 > > * GPU: nVidia Geforce GT240 (which carries a HDMI port and uses > the snd- > > * Receiver: Marantz SR7500 (supporting both Dolby Digital 5.1 > and DTS decoding), connected to motherboard's SPDIF TOSLINK port > (optical) + JBL 5.1 speaker-set > > * OpenElec 4.2.0: Kernel 3.16.3, Alsa 1.0.28 > > > > > > Symptoms: > > Speaker-test does not produce any sound.
