[OpenIndiana-discuss] OI Audio System Selects Wrong Audio Device

[Gary Mills]

My OI system ryzen has two audio devices.  Here are the links:

<mills at ryzen:2362>$ ll /dev/sound/?
lrwxrwxrwx   1 root     root           9 Sep 20  2017 /dev/sound/0 -> audiohd:0
lrwxrwxrwx   1 root     root           9 Sep 20  2017 /dev/sound/1 -> audiohd:1

When I attempt to play audio on these links directly, I get this:

<mills at ryzen:2363>$ audioplay -d /dev/sound/0 /usr/demo/SOUND/sounds/rooster.au
/* Complete silence */

<mills at ryzen:2364>$ audioplay -d /dev/sound/1 /usr/demo/SOUND/sounds/rooster.au
/* The rooster crows and dawn breaks */

/dev/sound/0 is the HDMI audio device.  /dev/sound/1 is the
motherboard audio device.  Here they are in scanpci:

pci bus 0x0008 cardnum 0x00 function 0x00: vendor 0x1002 device 0x677b
 Advanced Micro Devices, Inc. [AMD/ATI] Caicos PRO [Radeon HD 7450]

pci bus 0x0008 cardnum 0x00 function 0x01: vendor 0x1002 device 0xaa98
 Advanced Micro Devices, Inc. [AMD/ATI] Caicos HDMI Audio [Radeon HD 6450 /
 7450/8450/8490 OEM / R5 230/235/235X OEM]

pci bus 0x000a cardnum 0x00 function 0x03: vendor 0x1022 device 0x1457
 Advanced Micro Devices, Inc. [AMD] Family 17h (Models 00h-0fh) HD Audio
 Controller

These are the device links:

lrwxrwxrwx   1 root     root          68 Sep 20  2017 audiohd:0 ->
 ../../devices/pci at 0,0/pci1022,1453 at 3,1/pci1043,aa98 at 0,1:sound,audio0
lrwxrwxrwx   1 root     root          68 Sep 20  2017 audiohd:1 ->
 ../../devices/pci at 0,0/pci1022,1454 at 8,1/pci1043,86c7 at 0,3:sound,audio1

In the Sound Preference MATE GUI, from the System menu, the Hardware
tab is empty, leaving no way to select an audio device.  The Input and
Output tabs show only one device, also leaving no way.

As a result, there's no way to select second audio device, the one
that's built-in to motheboard with audio jacks.  The first audio
device is the one that produces no sound.  It behaves this way because
the audio driver ignores HDMI audio, a known illumos bug.

Is there any way to fix this system?  I'd like to use Youtube again.
