Bose with Xfce/Arch Linux

Arch Linux に慣れてくると本当に便利だ。わがBose Music System で音を聴きたい。早速検索すると、すぐ答えがこのサイトにあった! 有り難い。★以下は、Xfxeの場合:

In order to get ALSA to work with your Bose speakers (after you have properly configured ALSA):
The trick is to set a new default device for ALSA.
First, run

$ cat /proc/asound/cards

My sample result:

0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xfdff8000 irq 16
1 [Audio ]: USB-Audio - Bose USB Audio Bose Corporation Bose USB Audio at usb-0000:00:1d.2-2, full speed

Look at /usr/share/alsa/alsa.conf and the find parameters you need to edit.

# defaults
defaults.ctl.card 0
defaults.pcm.card 0

Change the default number on both values to the number that corresponds with your card. In my case, this is 1.
Then, select the device in System > Preferences > Sound (for Gnome) and change Alsa mixer volume settings.

これでOK! 全くのノートラブルで成功した。
