No sound on laptop

I've installed arch on a  old Toshiba Qosmio X505-Q892 which was purchased in 2011.

The sound is not working and it appears to be an issue with the snd_hda_intel module.

I have Toshiba's last released BIOS installed.

lspci -k | grep -A3 -i audio

00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)
	Subsystem: Toshiba Corporation Device ff50
	Kernel driver in use: snd_hda_intel
	Kernel modules: snd_hda_intel

So I unload the driver: rmmod snd_hda_intel

And it gets disabled above at:

Jul 24 13:38:06 toshiba kernel: snd_hda_intel 0000:00:1b.0: Codec #3 probe error; disabling it...

I going to give more info but the primary issue I think is above.

/etc/modprobe.d/sound.conf

softdep snd-hda-intel pre: snd-aloop post: snd-usb-audio

#  pcm_substreams controls the number of subdevices
options snd-hda-intel model=auto
options snd-aloop index=0 pcm_substreams=2
options snd-hda-intel index=1
options snd-usb-audio index=4

cat /proc/asound/cards

                      Loopback 1

                      HDA Intel MID at 0xf0900000 irq 32
 2 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xcbefc000 irq 17

I can start jackdbus, load  alsa_in,  alsa_out, and calf eq12.
All  the connection are made to the system playback_1 and playback2, and I see the audio signal from mpv but  there is no sound - because snd_hda_intel was disabled.

Do you have any suggestions as to what I might try to get this working?

Re: No sound on laptop

I am  wrong about the " Codec #3 probe error; disabling the sound.

I booted to a linux mint ISO and the sound is working on it with the same "Codec #3" error.

So I don't know what I'm missing with arch.

Re: No sound on laptop

I finally got sound working but I'm not sure exactly what changed.

My solution was to install pulseaudio (normally run only jackdbus).

pulseaudio 
pulasaudio-jack
pulseaudio-alsa 
pulseaudio
pavucontrol

1. I stopped jack from loading on login and rebooted.
2. After rebooting pulseaudio was running.
3. I then started jack & the ALSA -> Pulseaudio -> Jack plugin
4. Started a video playing  - No Sound
5. Opened PavUControl and under  Output Devices clicked the speaker/unmute and sound started working.

Note, I had checked that the sound was unmuted  in AlsaMixer  many times.

I stopped pulseaudio and uninstall everything associated with it and sound continues to work.

Someone please enlighten me as to what clicking unmute in pavucontrol changed on the system...
