I updated wiki. Ok, I have now compiled the alsa snapshot with the following: ../configure --with-cards=hda-intel --with-card-options=hda-hwdep,hda-reconfig,hda-codec-realtek,hda-codec-nvhdmi,hda-generic,pcm-xrun-debug --with-debug=verbose --enable-verbose-procfs --with-isapnp=no --with-sequencer=no --with-oss=no --with-pcm-oss-plugins=no Attached are samples of my dmesg and /var/log/syslog files. Hopefully there is some useful information there? Best regards, Derek
