raspberry cm4 + 光纖 做 Roon Bridge

alvinlee603

突發奇想 用 raspberry cm4 with IO Board + PCI-E NIC SFP + Ropieee 做 Roon Bridge，咁咪直接行光纖隔離。頂多加個 LPS，應該唔錯。
有冇師兄知道可唔可行？

首先 CM4 個 PCIe x1 slot 要加轉頭，否則 PCIe x4 嘅 NIC 插唔到入去個 slot，而且用轉頭再加埋 x4 變咗 x1 嘅玩法都唔知有咩影響：

然後師兄要上去 RoPieee 佢哋個 forum 問清楚最新嘅 kernel 版本有無 Intel X520 用嘅 driver 同埋 firmware：

https://pipci.jeffgeerling.com/cards_network/dell-intel-942v6-x520-da2-10gb-sfp-dual-nic.html

Arch Linux 用嘅 kernel module 就係呢個 file，師兄可以爆開 RoPieee 個 image 睇睇有定無：

kernel/drivers/net/ethernet/intel/ixgbe/ixgbe.ko.xz

假如無嘅話就可以放棄或者改用另一個 distro，其實師兄唔多熟 Linux 就真係無謂諗咁多，好多嘢未必係想像中咁簡單，而且 mainline kernel 版本要等到最新嘅 5.16 先至正式 support 得到 CM4，問題係 5.15 先至有 Long Term Support：

一睇就知道佢哋淨係用 LTS 嘅 kernel 版本：

理論上話 support 得到 CM4，實際上真正 support 得到幾多嘢就點都要用過先至知道：

https://ropieee.org/changelog/
https://community.roonlabs.com/t/stable-release-3-107-2021-05-08/158782

NEW: support for the Raspberry Pi Compute Module 4 IO Board

總之唔想做咁多功課嘅話就真係唔好諗住玩 Linux 嘢，反正瘦咗身嘅 Windows PE 已經遠超相當勁嘅 WTFPlay：

I´m sorry, I mean Win10XPE is VERY SUPERIOR TO WTFPlay.

Tl:dr: WTFPLAY >> Hysolid >>>> Winyl = Musicbee = Hqplayer = xmplay > Audirvana >> jriver = roon > Aimp > uapp on android > foobar2000 > any bundled music player with windows or non asio supported players.
