## Configuration

### Video

The `xf86-video-ati` driver is recommended, read [ATI](/index.php/ATI "ATI") for more information.

### Networking

**Note:** If you experience freezes when turning on the wireless card/connecting to wireless networks, select "Network Boot" as first boot device in the BIOS. (Press F2 during Acer boot screen to access the BIOS options.)

Wireless ethernet driver `brcmsmac` should automatically load at startup.

This should no longer be needed, but in the past, the modules `bcma` and `acer-wmi` caused conflicts and had to be [blacklisted](/index.php/Modprobe#Blacklisting "Modprobe").

Setup may be further configured by reading [Wireless network configuration](/index.php/Wireless_network_configuration "Wireless network configuration").

### Audio

Initially, audio doesn't work, except for beeping. The problem may be corrected by editing `/usr/share/alsa/alsa.conf` and replacing every instance of `card 0` with `card 1`. (This also works on the AO725-0488.)

As of kernel 3.1, the headphone jack is correctly supported.

For kernel versions < 3.1, a bash script may be used to switch between the internal speakers and headphones. First, download [hda-verb](https://aur.archlinux.org/packages/hda-verb/) from the AUR. The package is now out of date, so use the following PKGBUILD script:

```
pkgname='hda-verb'
pkgver=0.4
pkgrel=1
pkgdesc="Tool to send commands (verbs) to HD-Audio codecs"
arch=('i686' 'x86_64')
depends=('glibc')
url="ftp://ftp.suse.com/pub/people/tiwai/misc/"
license=('GPL')
source=(ftp://ftp.suse.com/pub/people/tiwai/misc/$pkgname-$pkgver.tar.gz)
md5sums=('60be775c58feb2f8b9644dfeca0ad0d8')

build() {
	cd $srcdir/$pkgname-$pkgver

	make || return 1
	install -D $pkgname $pkgdir/usr/bin/$pkgname
}

```

Next, save the following bash script:

```
#!/bin/bash

# If needed, change these to the pins of the headphones and speakers, can be found using hda analyzer
pin_headphones="0x19"
pin_speakers="0x1f"

case "$1" in
  [Hh]*)
    hda-verb /dev/snd/hwC1D0 "${pin_headphones}" \
      set_pin_wid 0xc0
    hda-verb /dev/snd/hwC1D0 "${pin_speakers}" \
      set_pin_wid 0x00
    ;;
  [Ss]*)
    hda-verb /dev/snd/hwC1D0 "${pin_headphones}" \
      set_pin_wid 0x00
    hda-verb /dev/snd/hwC1D0 "${pin_speakers}" \
      set_pin_wid 0x40
    ;;
esac
```

Run the script as root with h or s as an argument to switch to headphones or speakers. Sometimes the command must be run again if a new audio program is started. (Taken with modifications from [this discussion](https://bbs.archlinux.org/viewtopic.php?id=125522) in the forums.)

#### HDMI Audio issue

The hdmi video display works fine out of box (as of 2014-1-1, using ATI driver), however, HDMI audio doesn't work. Searching the forum, there is some indication this is due to video driver issue.

### Beep on Power Cord Plug-In/Out

To lower the loudness of the beep when the power cord to an acceptable level, open alsamixer, select the "HDA ATI SB" sound card using F6 and mute the "Beep" by using arrow chars and then pressing "m"

### Dual Boot

See [Windows and Arch dual boot](/index.php/Windows_and_Arch_dual_boot "Windows and Arch dual boot") for general information. Note that this netbook does **not** come with recovery CDs. If an attempt to set up dual boot goes awry and you can't boot the machine at all, or can't boot into Windows, you can restore the original Windows configuration by booting into /dev/sda1, the recovery partition, as if it were an ordinary Windows installation. The recovery program says it will wipe the whole disk but will only wipe the partition on which Windows resides. (You can install grub from the Arch installation media onto a thumbdrive and take it from there.)
