Failed to attach mixer

[mazaxaka]

I have shairport-sync installed on raspberrt pi with arch linux

config file is:

general =
{
   name = "Kitchen";
   interpolation = "basic";
   output_backend = "alsa";
   mdns_backend = "avahi";
};

alsa =
{
  output_device = "default";
  mixer_control_name = "PCM";
};

when i execute systemctl start shairport-sync and check status systemctl status shairport-sync

i get this

[root@alarmpi ~]# systemctl status shairport-sync
* shairport-sync.service - ShairportSync AirTunes receiver

Jul 30 23:24:42 alarmpi shairport-sync[186]: Failed to attach mixer

date on raspberry is incorrect

but when i execute shairport-sync -a kitchen -d 'default' -c Surround evrything is ok

what i'm doing wrong?

Hi there. thanks for trying Shairport Sync. You have given two different mixer control names – in the config file you've given "PCM" and in the command line, you've given "Surround". It looks like "Surround" is the right one...
