    A quick scan into the files you linked to shows that this could be due to the fact that CONFIG_MMC_SDHCI* modules are not built into the kernel but rather are modular which makes them being loaded too late in the boot process.
    Furthermore it looks like chtcx2072x.tar possibly overwrites /usr/share/alsa/ucm/chtrt5645/HiFi.conf which would cause your audio issues with my kernel.

    Bottom line: Switch to a stock kernel or my kernel, don't use a (rather old) kernel that was not built for this device.
    Ok, what do you recommed me to do?
    Yesterday I create a bootable USB with your kernel, but the wifi and the audio continue to not working. How can I resolve this issue? How can I load modules from boot process?

    Re: Asus X205TA hardware support in Ubuntu

    Oh wait! Now I see that my pc isn't a x205ta but an X206HA! I bought it from Amazon, last year but they send me an X206HA! It's incredible! I turned my pc and I read the model! So for this reason I haven't problem with audio and wifi! I've been so lucky to install this patch! -.-'
    So how can I load modules in boot? Any advise? Sorry if I continue to ask but you are the only person in all internet that give answer for this argument!

    EDIT:

    Looking around and making the right search (now I can do for X206HA) I found this that risolve all of my SD problems:
    Code:
    echo "80860F14:03" > /sys/bus/platform/drivers/sdhci-acpi/unbind
    echo "80860F14:03" > /sys/bus/platform/drivers/sdhci-acpi/bind
    Then with a simple systemd script all works well.

    Re: Asus X205TA hardware support in Ubuntu

    I seem to be having a problem getting WiFi to work.
    I've copied over brcmfmac43340-sdio.bin from this git repository: ( git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git )
    and also brcmfmac43340-sdio.txt from nvram ( /sys/firmware/efi/efivars/nvram-74b00* ) and put both of those files into /usr/lib/firmware/brcm and then restarted

    The device appears and I can see networks (using NetworkManager on KDE Plasma & also on nmtui) but I cannot connect to my home network.
    It repeatedly asks for my passphrase 3 times before it stops trying with "No secrets were provided" as the error message.

    It does occasionally work on public wifi after a few tries, but it absolutely refuses to work on my home wifi.

    My home wifi is configured as WPA Pre-Shared Key, WPA2 AES encryption, Automatic 20/40 MHz, Automatic Channel

    I'm using a self-compiled kernel with harryharryharry's configuration & the patches outlined in his post

    If this makes a difference, I live in Japan, might be some issue with crda perhaps?
    Thanks in advance for any help anyone might be able to give me

    Re: Asus X205TA hardware support in Ubuntu

    Looks like you properly addressed the x205ta-related wifi quirks, because the wlan0 device is present. (keep in mind 5.0ghz networks will not be visible with the nvram from the efi-directory).

    Might indeed have something to do with regulatory domain issues or wpa_supplicant/kwallet issues (googling these issues in combination with the error you get and your linux distro might yield some solutions).
    Maybe try from the command line first to see if it works or throws any errors:
    Code:
    #as root
    systemctl stop NetworkManager
    systemctl stop wpa_supplicant
    ps aux|grep -i "dhc\|wpa\|net"   ##check if any network managers or dhcp clients are still running (if so, you should kill them)
    wpa_passphrase YOUR_SSID >> /etc/wpa_supplicant/wpa_supplicant.conf   ##this will give you a prompt to enter your wpa password, and hit enter (you need to do this only once per ssid you wish to connect to)
    wpa_supplicant -D wext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf   ##for me this throws a ioctl error, but works fine anyway
    
    #and then from another terminal, as root:
    dhclient -i wlan0   ##or use another dhcp-client if you have it installed
    ping 8.8.8.8
    This might make you able to pinpoint whether the issue is wifi frequency or password related.

    You could try changing "Automatic Channel" on your router to any channel in the 1-11 interval. Channel 12 and 13 are not detected on my x205ta.

    Thank you very much for trying to help me

    I've done your instructions in the terminal; but it still won't connect!
    Code:
    [root@kasei ~]# wpa_supplicant -D wext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

    Since the error message appears to be "Timed out" I thought that maybe it might be a signal issue but I'm right beside the router!

    So from the output, my signal quality should be perfect?

    Also, after I try running wpa_supplicant, this is the output from # dmesg
    Code:

    I'm using Arch Linux; in case that has something to do with it;
    all the solutions I've found on google appear to relate to Realtek and Intel wifi cards so I don't know if they are relevant

    Again, thank you so much for helping, sorry for the trouble

    Re: Asus X205TA hardware support in Ubuntu

    Strange, I wouldn't really know what to make of it. The error messages are not really specific and seem to point to different problem areas. Those "ioctl[SIOCSIWENCODEEXT]: Invalid argument" errors are expected but the other ioctl-error (Resource temporarily unavailable) might indicate a problem with how linux is able to control the wifi chip.

    I think signal level=-25 dBm means a strong signal, freq=2412 means channel 1, which from what I've read should be no issue in Japan (but I'm not really sure). reason=3 locally_generated=1 doesnt really pinpoint the issue as I also get those codes when entering a wrong wpa-key (but in that case it is accompanied with a more descriptive error). On one hand auth_failure seems to indicate something is wrong with the key exchange, on the other hand - as you said - the timeout message seems to indicate somethings wrong with the communication (either the wifi-chips' signals don't reach the router or the router's signals don't reach the wifi-chip).

    Maybe it's easiest to go by trial and error: Boot for example from a liveusb my prebuilt xubuntu iso with my kernel, and see if you can connect to your network. If this works, you know nothing is wrong with the chip and/or router signal/frequency/encryption/etc..
    After that you can boot back into Arch and try to install my prebuilt kernel. If my kernel works you know somethings wrong with your kernel, otherwise somethings wrong with your arch install (maybe missing/malfunction crypto libs or wpa_supplicant related packages).

    Okay, so I've booted into the prebuilt xubuntu ISO but it still exhibits the exact same symptoms as my arch install!
    NetworkManager does the same thing where it asks for my wifi passphrase multiple times before failing, and manually connecting via wpa_supplicant also yields the exact same output as before!
    The X205TA is the only wireless device that can't connect to my home network; my 3DS, PS Vita, Android phone and old single-core AIO can all connect to it, factory resetting the router didn't help either

    I'm honestly at a loss here; Google isn't helping much either

    Oops, sorry! I wasn't aware that non-Ubuntu discussion wasn't allowed in the thread; from now on I'll be using the xubuntu live USB to troubleshoot, if that's okay?
