That is nice to know... Here is the deal: when I "% cat /dev/sndstat" it shows both pcm0 and psm1 as: HDA Conexant CX20561 (Hermosa) but not in the "verbose" output below from dmesg(8). Right now I have this (after some reformatting - no TABs either!): HDA Codec #0: Conexant CX20561 (Hermosa) HDA Codec #1: Conexant (Unknown) <<<<<===== not sure why this is Dumping AFG cad=0 nid=1 pins: nid 22 0x022140f0 as 15 seq 0 Headphones Jack jack 1 loc 2 color Green misc 0 Caps: OUT HP Sense: 0x 7fffffff nid 23 0x61a190f0 as 15 seq 0 Mic None jack 1 loc 33 color Pink misc 0 [DISABLED] Caps: IN VREF Sense: 0x 7fffffff nid 24 0x02a190f0 as 15 seq 0 Mic Jack jack 1 loc 2 color Pink misc 0 Caps: IN VREF Sense: 0x 7fffffff nid 25 0x40f000f0 as 15 seq 0 Other None jack 0 loc 0 color Unknown misc 0 [DISABLED] Caps: OUT Sense: 0x 7fffffff nid 26 0x901701f0 as 15 seq 0 Speaker Fixed jack 7 loc 16 color Unknown misc 1 Caps: OUT EAPD nid 27 0x40f001f0 as 15 seq 0 Other None jack 0 loc 0 color Unknown misc 1 [DISABLED] Caps: OUT EAPD nid 28 0x40f001f0 as 15 seq 0 Other None jack 0 loc 0 color Unknown misc 1 [DISABLED] Caps: OUT nid 29 0x90a601f0 as 15 seq 0 Mic Fixed jack 6 loc 16 color Unknown misc 1 Caps: IN After disregarding the DISABLED lines I have this: nid 22 0x022140f0 as 15 seq 0 Headphones Jack jack 1 loc 2 color Green misc 0 Caps: OUT HP Sense: 0x 7fffffff nid 24 0x02a190f0 as 15 seq 0 Mic Jack jack 1 loc 2 color Pink misc 0 Caps: IN VREF Sense: 0x 7fffffff nid 26 0x901701f0 as 15 seq 0 Speaker Fixed jack 7 loc 16 color Unknown misc 1 Caps: OUT EAPD nid 29 0x90a601f0 as 15 seq 0 Mic Fixed jack 6 loc 16 color Unknown misc 1 Caps: IN The snd_hda(4) man page does not discuss what "EAPD" is, nor what "VREF" is, nor what "HP" is. It also does not discuss "Caps:" but I can infer what "IN" and "OUT" are. :-) So, I have a speaker (big whoop) and two "jacks": one pink and one green (but I already knew that, too). I note that there is only one AS (15, or is that 14?) and only one "seq" (0) which doesn't mesh well with your earlier T400 suggestion: > hint.hdac.0.cad0.nid22.config="as=1 seq=15" > hint.hdac.0.cad0.nid24.config="as=3" > hint.hdac.0.cad0.nid26.config="as=1" > hint.hdac.0.cad0.nid29.config="as=2" For example, where did 'AS'es 1, 2, 3 come from? And where did "seq" 15 come from? :-( However, it is mighty curious that your four "nid"s match my four non-DISABLED "nid"s - hmmm... :-) Recognizing from your comments above that you may not be able to answer these rhetorical questions, but if I just try your suggestions "blind" what are the chances it will "just work" for me? I do hate just copying something without knowing what the heck it means -- just the pedantic engineer in me, I reckon... :-) The snd_hda(4) man page is not very helpful in explaining what your four hints would do for my T500 problem, but I guess it is worth a try.
