[SOLVED] Bit Resolution in /etc/pulse/daemon.conf ignored by alsa sink

I followed this guide: https://wiki.archlinux.org/index.php/Ad … und.state) to reset the Alsa settings but my bit resolution keeps being set to 32. When I run 

pacmd list-sinks

I get:

1 sink(s) available.

		alsa.components = "HDA:10ec0887,1458a184,00100302"
		device.icon_name = "audio-card-analog-pci"

even though my /etc/pulse/daemon.conf is:

resample-method = speex-float-5
flat-volumes = no

 default-sample-format = s24le
 default-sample-rate = 192000

 default-fragments = 3
 default-fragment-size-msec = 5

I want the bit resolution to be 24 but the alsa sink keeps reporting the alsa.resolution_bits as 32. So either I'm not following the directions correctly, the default is being misread, or something else I'm not seeing.

Re: [SOLVED] Bit Resolution in /etc/pulse/daemon.conf ignored by alsa sink

I'm guessing the hardware can't do 24 bit. It perhaps only can do 16 and 32 bit formats?

You can check out what the hardware can do in the files named "/proc/asound/card*/codec#*". You can first find out which of the card* folders are your motherboard's device like this:

$ tail /proc/asound/card*/id
==> /proc/asound/card0/id <==
HDMI

==> /proc/asound/card1/id <==
Generic

This example means that for me here the motherboard is "card1", the graphics card is "card0".

I can then check the "codec#*" file in that "card1" folder:

less /proc/asound/card1/codec*

The interesting stuff I see here is:

Codec: Realtek ALC1220
...
Node 0x02 [Audio Output] wcaps 0x41d: Stereo Amp-Out
  Control: name="Front Playback Volume", index=0, device=0
...
  Device: name="ALC1220 Analog", type="Audio", device=0
...
  PCM:
    rates [0x7e0]: 44100 48000 88200 96000 176400 192000
    bits [0x1e]: 16 20 24 32
    formats [0x1]: PCM
...
...
...
Node 0x06 [Audio Output] wcaps 0x611: Stereo Digital
...
  Device: name="ALC1220 Digital", type="SPDIF", device=1
...
  PCM:
    rates [0x5f0]: 32000 44100 48000 88200 96000 192000
    bits [0xe]: 16 20 24
    formats [0x1]: PCM
...

For the "card0" device that's my graphics card (meaning my monitor's speakers), I see this here:

Codec: ATI R6xx HDMI
...
Default PCM:
    rates [0x70]: 32000 44100 48000
    bits [0x2]: 16
    formats [0x1]: PCM

Re: [SOLVED] Bit Resolution in /etc/pulse/daemon.conf ignored by alsa sink

For these values to be accurate you have to be playing something, do you know that your card actually supports 24le ? pulse will only honor this for cards that actually support what you are specifying.

If you want to know what your card supports, cease all playback (and since you seemingly disabled suspension, stop pulseaudio), compile

this piece of code, run 

./hw_params hw:1

post/check the output. I still think you are chasing a red herring here with an issue that doesn't seem software related, and you do many misguided changes in an attempt to resolve them. I still think the best "test" you can do here is stop pulseaudio, configure MPD to directly access hw:1 and check if you can still reproduce the high CPU crackling issue. If you can you can knock yourself out however you want it's unlikely you'll be able to fix this with pulseaudio configuration.

Codec0 is my graphics card which I don't use for audio. It appears it does support 24 bit audio but not 32. If that's the case, I don't see why it wouldn't honor my setting.

For these values to be accurate you have to be playing something, do you know that your card actually supports 24le ? pulse will only honor this for cards that actually support what you are specifying.

If you want to know what your card supports, cease all playback (and since you seemingly disabled suspension, stop pulseaudio), compile

this piece of code, run 

./hw_params hw:1

post/check the output. I still think you are chasing a red herring here with an issue that doesn't seem software related, and you do many misguided changes in an attempt to resolve them. I still think the best "test" you can do here is stop pulseaudio, configure MPD to directly access hw:1 and check if you can still reproduce the high CPU crackling issue. If you can you can knock yourself out however you want it's unlikely you'll be able to fix this with pulseaudio configuration.

I compiled and ran that code with the hw:1 argument and got:

Device: hw:1 (type: HW)
Access types: MMAP_INTERLEAVED RW_INTERLEAVED
Formats: S16_LE S32_LE
Channels: 2
Sample rates: 44100 48000 96000 192000
Interrupt interval: 83-11888617 us
Buffer size: 166-23777234 us

That seems contradictory to the output I got from 

most /proc/asound/card1/codec*

(see above).

Re: [SOLVED] Bit Resolution in /etc/pulse/daemon.conf ignored by alsa sink

One of them is a piece of information about what the codec should support and the other is actual evidence as to what the hardware ends up responding to when asked. Something is definitely weird here in regards to how your card is initialized. IIRC you did mention Windows in your other thread, if that is setup as a dual boot, have you ensured that fastboot is disabled ? If you've done that one thing you can try if windows or your BIOS/UEFI (it has been a while since we last talked about this, which motherboard brand is this?) sets up your card in a weird state is running 

sudo alsactl init

that should enforce the card to be initialized according to the codecs specification rather than what's reported by the firmware.

Do you currently have any logical adjustments with regards to snd_hda_intel in modprobe.d or so? What's your output for 

sudo journalctl -k | grep -E 'hda|snd|codec'

My output for 

sudo journalctl -k | grep -E 'hda|snd|codec

is:

Fast boot is turned off or on within Windows correct? At first I thought of "secure boot" but I know that's BIOS related. I think I set "fast boot" off when I first installed Ubuntu (no longer on my system) but I'll double check. I currently dual boot Arch with Windows 10 using Grub. Both boot with UEFI.

EDIT: I am dual booting with Windows 10 so I followed the guide from the link in the arch wiki section you linked. I used the first option with the control panel but I didn't see the setting even listed. I'll try the option when you use a bat file to disable fast startup just to be sure.
EDIT2: I ran the bat file to disable fast startup. I also disabled hibernation by running a command in command prompt from this guide: https://www.pugetsystems.com/labs/suppo … ation-793/ since the option wasn't available in power options in control panel to be sure.
