ArchQ 數位訊源入門 -> 究極

[sam0402]

目前是單機設定,,引上設定還是沒聲音,請問會是ddc usb轉同軸問題嗎?

小弟也是用USB DDC -> 同軸 -> DAC。

su
update_scpt.sh
tinymix controls

看看是否有列出DDC。
---
若沒有，重裝一次 TinALSA

wget -P /tmp https://raw.githubusercontent.com/sam0402/ArchQ/main/pkg/tinyalsa-evl-2.1-1-x86_64.pkg.tar.zst
pacman -U --noconfirm /tmp/tinyalsa-evl-2.1-1-x86_64.pkg.tar.zst
tinymix controls

---
若有，先改用 config -> server -> mpd(非net) -> Squeezelite 的方式，看看能不能出聲。
需要先了解哪一段出問題。

[root@ArchQ:Q352WU admin]# tinymix controls
Number of controls: 3
ctl type num name device
0 INT 2 Playback Channel Map 0
1 BOOL 1 PCM Playback Switch 0
2 INT 1 PCM Playback Volume 0
確認DDC接電腦ok,,先format intel 10G重灌看看

改用squeezelite 出現
Failed to enable unit: Unit file squeezelite.service does not exist.

目前改設myMPD MPD(slim out) 沒聲音,,但音樂播放秒數有在跑但2分後出現MPD disconnected;之前設pcmrecv跑35秒就停出現錯誤卡住

請問sam大單機安裝順序是 server -> MPD(slim out)再設MPD->再設player ->squeezelite嗎
MPD-Net -> mympd ->mpd->player-Pcmrecv ?

[sam0402]

是喔！
Server -> Mpd Slim
Player -> Squeezelite
可以用 systemctl status mpd squeezelite 確認
Squeezelite <-> pcmrecv 同時只能啟動一個，不然會搶音效卡。
可以用config -> player 來選擇 enable/disable

請教sam大 service mode是要設?

[admin@ArchQ:Q352WU ~]$ systemctl status mpd squeezelite

Squeezelite 沒安裝到，用 config -> player -> squeezelite

請教sam大 service mode是要設?

這個不用管它，是給開機時，想要啟動不同服務用的設定。
新天新地現在不太順，沒法給說明頁。可先問Ai: ArchQ service mode

,星期一在試


再請教一個問題主畫面 S Pcmrecv 跟 config -> player ->Pcmrecv 有何不同?

[sam0402]

sudo sqzlite-cfg.sh
用這個方式安裝squeezelite

[chgeorge]

cat /proc/asound/cards 0 [Audio ]: USB-Audio - USB Audio C-Media INC. USB Audio at usb-0000:00:14.0-4.3, full speed


有了這個硬體資訊，答案完全水落石出了！
錯誤的根源就在於：您的 USB DAC 是一隻 C-Media 晶片的基礎 USB 音效裝置 (卡號為 0)。這類微型晶片在硬體規格上有兩個致命限制：

• 不支援 24-bit 傳輸格式 (S24_3LE)：它通常只吃標準 16-bit (S16_LE)。
• 完全無法承受 TinyALSA 極致發燒的超低緩衝設定 (-p 64)。

立馬去淘一個DDC,,squeezelite就不搞了,,專心執行Mpd-net -Pcmrecv
