Solaris10: áudio para usuários

  • 772

A situação antes de eu fazer login no desktop CDE (ou Gnome)

mplayer Taste\ of\ freedom-A\ man\ sing\ his\ song.mp3 
MPlayer 1.1-4.8.2 (C) 2000-2012 MPlayer Team

Playing Taste of freedom-A man sing his song.mp3
libavformat version 54.6.100 (internal)
Audio only file format detected.
Load subtitles in ./
==========================================================================
Opening audio decoder: [mpg123] MPEG 1.0/2.0/2.5 layers I, II, III
AUDIO: 48000 Hz, 2 ch, s16le, 320.0 kbit/20.83% (ratio: 40000->192000)
Selected audio codec: [mpg123] afm: mpg123 (MPEG 1.0/2.0/2.5 layers I, II, III)
==========================================================================

[AO SUN] Can't open audio device /dev/audio, Permission denied  -> nosound.
[AO ESD] esd_open_sound failed: No such file or directory

Eu entro no CDE, entro remotamente na máquina Solaris (ou localmente) e voilà

MPlayer interrupted by signal 2 in module: play_audio

Minha pergunta é: quem muda a permissão? Qual arquivo modificar para tornar essas permissões permanentes mesmo sem logar no cde ou gnome?

Vejo que os dispositivos que alteram as permissões são estes:

143130628      1 crw-------   1 myuser other    273,   0 Jan 15 00:14 /devices/pseudo/oss_sadasupport@0:sound,audio
143130630      1 crw-------   1 myuser other    273,   1 Jan 15 00:14 /devices/pseudo/oss_sadasupport@0:sound,audioctl

    Na verdade, como solução alternativa, eu uso um bom e velho script estilo SysV vim /etc/rc3.d/S80rclocal

    #!/opt/csw/bin/bash

case "$1" in
'start')
PATH=$PATH:/opt/csw/bin
export PATH

for file in /devices/pseudo/oss_sada*;do sudo gfind $file -not -type d -exec gchown -c mysuser {} \;; done
    ;;
'stop')
true
    ;;
*)
    echo "Usage: $0 { start | stop }"
    exit 1
    ;;
esac
exit 0
