This may be the wrong forum for my questions, but this is where I was directed by an Intel representative.
tl/dr: What Realtek audio codec is used on the Intel N3530?
System is PCBSD10.1 (FreeBSD 10.1) on a N3530. Symptoms are:
sndstat shows two devices:
pcm0: (play/rec) default
Pin configurations that seem to matter:
hdaa0: Patched pins configuration:
hdaa0: nid 0x as seq device conn jack loc color misc
hdaa0: 18 90a60130 3 0 Mic Fixed Digital Internal Unknown 1
hdaa0: 20 90170110 1 0 Speaker Fixed Analog Internal Unknown 1
hdaa0: 33 0321101f 1 15 Headphones Jack 1/8 Left Black 0
hdaa0: Association 0 (1) out:
hdaa0: Pin nid=20 seq=0
hdaa0: Pin nid=33 seq=15
hdaa0: Association 1 (3) in:
hdaa0: Pin nid=18 seq=0
hdaa0: Tracing association 0 (1)
hdaa0: Pin 20 traced to DAC 2
hdaa0: Pin 33 traced to DAC 2 and hpredir 0
hdaa0: Association 0 (1) trace succeeded
hdaa0: Tracing association 1 (3)
hdaa0: Unable to trace pin 18 to ADC 8, undo traces
hdaa0: Unable to trace pin 18 to ADC 9, undo traces
hdaa0: Pin 18 traced to ADC 17
hdaa1: Patched pins configuration:
hdaa1: nid 0x as seq device conn jack loc color misc
hdaa1: 4 18560010 1 0 Digital-out Jack Digital 0x18 Unknown 0
hdaa1: 5 58560020 2 0 Digital-out None Digital 0x18 Unknown 0 DISA
hdaa1: 6 58560030 3 0 Digital-out None Digital 0x18 Unknown 0 DISA
hdaa1: 1 associations found:
hdaa1: Association 0 (1) out:
hdaa1: Pin nid=4 seq=0
hdaa1: Tracing association 0 (1)
hdaa1: Pin 4 traced to DAC 2
GPIO state from sysctl:
dev.hdaa.0.gpio_state: 0=output(1) 1=disabled 2=disabled
dev.hdaa.0.gpio_config: 0=set 1=keep 2=keep
pcm1 seems to be related to HDMI, but I get noise out of the regular sound system if i run one of the sound tests against it. According to the pin settings, pcm0 is supposed to be the regular sound system. Also, I cannot send an audio file to the dsp device corresponding to pcm1. That is supposed to be the most basic sound test there is, but it does not work.
What sound codec is used on the N3530? That information may help.
Is there anything unusual about the way the sound system on the N3530 is designed?
What sorts of misconfigurations could potentially cause these of problems?
