Hello, I've setup a brand new computer from scratch, it has two HDMI output (via the on board and via the ati graphic card) with one codec for the main board. Usually I have these pcm : pcm0: <HDA ATI R6xx HDMI PCM #0 HDMI> at cad 0 nid 1 on hdac0 pcm1: <HDA Realtek ALC888 PCM #0 Analog> at cad 0 nid 1 on hdac1 pcm2: <HDA Realtek ALC888 PCM #1 Analog> at cad 0 nid 1 on hdac1 pcm3: <HDA Realtek ALC888 PCM #2 Digital> at cad 0 nid 1 on hdac1 pcm4: <HDA Intel G45 HDMI PCM #0 DisplayPort> at cad 3 nid 1 on hdac1 But sometime when I boot the pcm4 disappear, with a lot of : hdac1: hdac_widget_connection_parse: nid=2 WARNING: zero cnid entnum=4 j=0 index=0 entries=17 found=0 res=0x00000000 hdac1: hdac_widget_connection_parse: nid=2 WARNING: zero cnid entnum=4 j=1 index=0 entries=17 found=1 res=0x00000000 hdac1: hdac_widget_connection_parse: nid=2 WARNING: zero cnid entnum=4 j=2 index=0 entries=17 found=2 res=0x00000000 hdac1: hdac_widget_connection_parse: nid=2 WARNING: zero cnid entnum=4 j=3 index=0 entries=17 found=3 res=0x00000000 [.. snip ..] Here you can see the normal dmesg file : http://files.malikania.fr/normal.txt And here when the pcm disappear : http://files.malikania.fr/notnormal.txt A simple diff from the files show some weird things: diff -ub normal.txt notnormal.txt --- normal.txt 2011-03-10 08:06:14.000000000 +0100 +++ notnormal.txt 2011-03-10 08:06:18.000000000 +0100 @@ -116,24 +116,90 @@ hdac0: HDA Codec #0: ATI R6xx HDMI pcm0: <HDA ATI R6xx HDMI PCM #0 HDMI> at cad 0 nid 1 on hdac0 hdac1: HDA Codec #0: Realtek ALC888 -hdac1: HDA Codec #3: Intel G45 HDMI +hdac1: HDA Codec #3: Intel Q57 HDMI +hdac1: hdac_widget_connection_parse: nid=2 WARNING: zero cnid entnum=4 j=0 index=0 entries=17 found=0 res=0x00000000 +hdac1: hdac_widget_connection_parse: nid=2 WARNING: zero cnid entnum=4 j=1 index=0 entries=17 found=1 res=0x00000000 [... message repeated a lot of time ...] pcm1: <HDA Realtek ALC888 PCM #0 Analog> at cad 0 nid 1 on hdac1 pcm2: <HDA Realtek ALC888 PCM #1 Analog> at cad 0 nid 1 on hdac1 pcm3: <HDA Realtek ALC888 PCM #2 Digital> at cad 0 nid 1 on hdac1 -pcm4: <HDA Intel G45 HDMI PCM #0 DisplayPort> at cad 3 nid 1 on hdac1 Why does the HDMI codec is renamed to Q57? I didn't tweak snd_hda(4) much, I only added the following in my /boot/devices.hints to get a proper jack-sense on my front panel: hint.hdac.1.cad0.nid27.config="as=1 seq=15" Cheers, -- David Demelier
