    山姆兄,您要的資料 PM 給您了。
    您的 kernel 使用 mpd 和 hqplayer 都沒問題。
    我原本猜是 udev 分配權限的問題,但又好像不是。
    這下難查了!其他的軟體可以播放,看來不是Sound Card Driver的問題。
    如果是Squeezelite的問題,在官方的Kernel 又可以???

    小弟Compile 的Squeezlite可用否?
    或許要看 /var/log/squeezelite 的 log 來debug了。

    感謝山姆兄,本來想等個幾天再看看,沒想到你戰鬥力這麼強。
    這個版本可以用了,而且您的 squeezelite 超級好聽。

    不過查了一下 log 檔,還是有出現一些 error

    因為我沒環境試,所以alsa-lib聲音有更好?
    如果是,這樣pCP8的經驗全用在x86了。

    相當便宜的組合,用雙 Xeon CPUs 的單機來跑 HQP+NAA 或者 LMS+Squeezelite 就爽歪歪了:

    https://audiophilestyle.com/forums/t...omment-1075198
    And he kindly helped to assure me that it is OK and he further offered to help me install a NAA in the same extreme computer making use of the two CPUs available. And I certainly would like to give it a try. So next up is the extreme HQ+NAA. And that's a WOW. The performance just leaps to another level. The presence , the focus as well as the soundstage all goes to another level. the string quartet now just sits right in front of you. The improvement in orchestral piece is not as obvious in the chamber music or jazz or unaccompanied voice. But it is the clear winner. This confirms my experience of using a NAA together with HQplayer is always beneficial and a NAA using optimised computers like the extreme actually helps tremendously to boost the SQ. It has all along been my experience that the better computer used as NAA the better is the sound.
    https://audiophilestyle.com/forums/t...omment-1075205
    I am also enjoying HQP+NAA on the Extreme, and there is indeed an SQ bump from separating the noisier (relatively, since PCM upsampling is very light) HQPlayer process doing upsampling and the NAA doing rendering onto different processors. This is just another example of why having 2 physical NUMA nodes (aka processors) enables a raft of optimizations that were just not possible on my single processor custom server.
    https://audiophilestyle.com/forums/t...omment-1079668
    Software changes on this computer make almost as much difference as a clock. I keep tweaking it and it keeps sounding better and better. The last experiment I've done, inspired by @austinpop and @romaz was to install HQplayer with affinities on one CPU and NAA with affinities to the other CPU. It's good to have two processors! I also created a loopback interface with ipv6. And I used ipv6 via the loopback interface to stream from the HQP to NAA. No upsampling, just using HQP as a bit perfect player. This brought the server that was sounding so great already to yet another level. Everything sounds so effortless now.

    支援Squeezeilte和有HDMI的音效輸出的功能
    看來可以跳過樹莓派了,就好像 2020 年剛剛起步的時候那種 HDMI → I²S 方法,而這個版本比較像樣:

    HDMI/MHL數字界面 分離提取音頻I2S/DSD/光纖/同軸 HDMI轉I2S/IIS

    https://item.taobao.com/item.htm?id=573460909636

    外國的樂友也是選擇同類型的產品:

    https://forum.psaudio.com/t/it-works...2s-input/15630



    雖然只是支援同軸輸出,但是對岸的樂友試過 eARC 的效果也可以接受,或許 HDMI 輸出的音效並非那麼糟糕?
