Weird messages from pulseaudio and wpa_supplicant

Hi! I have installed Archlinux but I found some problems in the “journalctl -p 3 -xb", so I would like to solve the following messages that I am receiving although I have good sound and both the wifi dongle and the usb adapter work well:

1)

pulseaudio[1508]: Failed to find a working profile.
pulseaudio[1508]: Failed to load module "module-alsa-card" (argument: "device_id="2" name="pci-0000_04_00.1" card_name="alsa_card.pci-0000_04_00.1" namere>
pulseaudio[1508]: GetManagedObjects() failed: org.freedesktop.systemd1.NoSuchUnit: Unit dbus-org.bluez.service not found.
pulseaudio[1508]: ALSA woke us up to write new data to the device, but there was actually nothing to write.
pulseaudio[1508]: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers.
pulseaudio[1508]: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

2)

wpa_supplicant[930]: nl80211: kernel reports: Authentication algorithm number required
wpa_supplicant[930]: bgscan simple: Failed to enable signal strength monitoring

What mean those messages?

Please, tell me if you need more data about my system. Thank you in advance!

Re: Weird messages from pulseaudio and wpa_supplicant

All of these read harmless. If you do not feel like you are missing a soundcard in pulseaudio there seems to be a detection issue with a specific card here you can ignore the first two messages (... otherwise you will want to post the untruncated, unpaged output as well as

aplay -l
lspci

) The lines after that have normal explanations, the bluetooth lines happen when pulse checks for bluetooth support but the relevant daemon not being enabled, the one after that is a common "issue" with the way USB devices are woken up without a detrimental effect in most cases (... it's been delegated to debug level in current master)

The second ones are wpa_supplicant trying to use certain features that your wifi adapter doesn't appear to provide, if you don't notice connection issues that can likely be ignored as well, what wifi driver/chipset is in use here, I'm guessing some realtek device? They are known for having driver issues like that not much you can do here and shouldn't be that much of an issue if you do not notice anything off

Re: Weird messages from pulseaudio and wpa_supplicant

Thank you for your answer. I read that the new kernels have some problems with a Qualcomm bluetooth device which is in my computer. Perhaps this could have caused the messages related with the bluetooth, since the bluetooth service is not enabled on my system because I am not able to use it yet. Then, I use a wifi usb adapter which is a Realtek RTL8812AU and works really well with the AUR package rtl8812au-dkms-git.

I understand that those messages in a way are inoffensive because I can use both my audio and my wifi. Either way, I will post my some of my outputs since it could be useful to others users:
