retitle 660111 [linux-image-3.2] ALC269VB HDMI single physical port -> multiple devices detected quit
After some online searching for this card's codec alc269vb I found several reports (some very old...) of the problem in Arch Linux: https://bbs.archlinux.org/viewtopic.php?id=133222 They point to a solution which is no longer documented. However, I did some more digging around and found a workaround: ftp://download.nvidia.com/XFree86/gpu-hdmi-audio-document/gpu-hdmi-audio.html#_pulseaudio_default_device or http://wiki.xbmc.org/index.php?title=HOW-TO:Setup_HDMI_audio_on_GeForce_GT210,_GT220,_or_GT240#PulseAudio_Configuration or http://www.mail-archive.com/pulseaudio-discuss@mail.0pointer.de/msg07433.html However, all these discussions point to NVIDIA cards, which are known for having several HDMI ports available. My laptop only has one, which in case of the 3.0.x kernel was assigned to the default HDMI alsa device #3 (and pulseaudio had no trouble using it). Now with kernel 3.2.x, my card appears to have 3 HDMI ports. The one on device #3 is no longer the actual connector on the laptop, but device #7 is, however pulseaudio only loads the first device by default. The workaround, as listed in the 3 links provided, is to force pulse to load the device that actually works adding this line to /etc/pulse/default.pa load-module module-alsa-sink device=hw:0,7 This works, I have just tested it. But I don't understand why my device, having only one physical output can be detected as having three, this is why I think the bug report should remain open. Furthermore this workaround hinders me from manually choosing the output device on pavucontrol as I did before, thus I cannot use the laptop speakers.. Should a bug report be filed against pulseaudio for lacking the capability to handle several HDMI outputs? I'm of the opinion that this is not necessary seeing as they are already aware of the problem. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
