其實之前都有聽其他師兄講過呢件野，不過我一直用開Logitech squeezebox touch 好滿意又懶得轉。近來忙完一輪心癢癢，所以就於上星期同hkborn師兄借左呢件野

甚麼是 Voyage Mpd?

個 size 好似一個 VHS 錄影帶8成咁大啦, 輕輕的... 可以話無多餘野(無 VGA), 個 serial port 對我嚟講都係多餘 (因為我無 serial cable, 旺電買條 9pin serial->usb 要 $98 )

甚麼是 Voyage Mpd?
呢件野其實係乜？好多人都唔知，我借得野出得報告就唔會只講聽感。因為如果你唔知係乜，知聽感有屁用咩。

首先，呢個盒叫 Voyage Mpd starter kit。Voyage 係一個由香港人自行從 Debian 中開發的 Linux distro. Linux 本身係一個OS（作業系統，或英文operating system), 但唔係實質OS產品。好似你話"Windows",佢都唔係一個實OS product. 只有"Windows XP", "Windows 7" 先係。所以，"Linux distro"係泛指所有的Linux product. 而"Voyage"就係一個Linux distro。

無個Linux distro 都有佢嘅賣點，否則唔使多舊魚整個新distro啦。呢個 Voyage 原意好簡單，就係要好簡單。只要最基本的系統服務令到一部電腦可以做到一個簡單任務。簡單如只係做voice over IP (好似Skype 果類），或者做network router, firewall....要咁簡單因為個電腦嘅硬件可能係好輕盈，可能只係intel core i3 嘅十分一速度，只有128m ram之類。

About Voyage Linux sticky icon       

Voyage Linux is Debian derived distribution that is best run on a x86 embedded platforms such as PC Engines ALIX/WRAP, Soekris 45xx/48xx/65xx and Atom-based boards.

It can also run on low-end x86 PC platforms. Typical installation requires 128MB disk space, although larger storage allows more packages to be installed. Voyage Linux is so small that it is best suitable for running a full-feature firewall, wireless access point, Asterisk/VoIP gateway, music player or network storage device.

咁 MPD 又係乜? MPD 全名係 'Music Player Daemon':
http://mpd.wikia.com/wiki/Music_Player_Daemon_Wiki

Music Player Daemon (MPD) is a flexible, powerful, server-side application for playing music.

Voyage 作者 Punky Tse (謝先生)佢見個 MPD 加左去 Voyage 好似幾有殺着, 所以就搵左個好"雞"嘅 x86 embeded system (http://www.mini-box.com/Alix-3D-Board-2-LAN-1-MINI-PCI-1_2) 實行一件過出個 Voyage Starter Kit. 入面包左:
1. ALIX.3d2
2. 4G CF Card (load 左最新的 Voyage + MPD)
http://store.voyage.hk/

Punky兄佢另一邊廂就專心繼續攪個 Voyage. 好似最新出的 version 0.9 release candidate 1 就加左 DSD over PCM (DoP) support. 我本身無乜高清音樂, 也無 DSD DAC, 所以唔知點 set. 不過估計好多野要 work 到唔係單單個 player (MPD) support 就得, 仲要個 operating system (Voyage) support. 當然, DAC / DDC 都要 support 啦.

對好多人嚟講, Linux 個 CAS 唔容易, 仲要無 screen!!! 但其實 Voyage Start Kit 已經將呢個痛苦隠藏左 (當然, 你可以將呢D煩野揾出來自煩一番). 如果你用 Voyage Starter Kit, 你只需要駁 LAN cable (一定要), 插隻有歌 (WAV, FLAC, AIFF, MP3, ...) 嘅 USB 手指 同 DC 12V, 等1/2分鐘就可以係 iphone / ipad 見到同播歌.

你會問:
1. 如何關機?
可以唔關, 因為食好少, 好少電. 但如果要關, 我會就咁 unplug 個電源 (因為technically speaking, 個 file system 係 mount as read-only)
2. 如何升級 voyage / mpd?
其實如果佢好地地, 你係唔建議升級的, 因為唔一定好左, 但如果你想做, 咁可以:
2.1. 單買一張 CF Card (http://store.voyage.hk). 換左張 CF card 就可以
2.2 自己攪 (download new Voyage + MPD, extract it, run voyage.update script....)

佢只會出 USB, 所以你要加一個有 USB 的 DAC, 市面上好多呢類DAC. 也可加個 DDC (digital-to-digital convertor) 先駁 DAC, 將 USB 轉為 coaxial / tsolink / AES / I2S.
