Subject: Re: [DNG] ALSA: Host is down

After restarting X server on Daedalus I lost audio. I posed a
question but the thread got hung up on PulseAudio. I have pipewire
instaled but not PulaeAudio. I havve no desktop.

When I try to open alsamixer I get the error:
"cannot open mixer: Host is down"

No problem if I specify which card to use

    $ alsamixer -c0


    The card is HDA Intel PCH


The sound system works

    $ aplay test.wav


But when I try to use audacity to play a CD I get the error

    ALSA error: snd_pcm_open failed: Host is down.


I try mplayer without luck

    $ mplayer -cdrom-device /dev/cdrom cdda // 
    MPlayer UNKNOWN-12 (C) 2000-2023 MPlayer Team


    Playing cdda.
    File not found: 'cdda'
    Failed to open cdda.


    Playing //.
    Cache fill:  0.00% (0 bytes)


    libavformat version 59.27.100 (external)
    Exiting... (End of file)


But alsaplayer works just fine!

    $ alsaplayer /dev/cdrom CD.cdda


I constructed a ~/.asoundr file in which I specify the card to be 0,
but this did not help


    pcm.!default {
        type plug
        slave.pcm "dmixer"
    }


    pcm.dmixer  {
        type dmix
        ipc_key 1024
        slave {
                pcm "hw:0,0"
                period_time 0
                period_size 1024
                buffer_size 4096
                rate 44100
        }
        bindings {
                0 0
                1 1
        }
    }


    ctl.dmixer {
        type hw
        card 0
    }
