[Voyage-linux] Voyage MPD & alsaequal

[Navas Abubacker]

Hi Punky,

Thanks for your reply and yes you are right

 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 4644 mpd       20   0 73816  14m 6688 S 97.1  6.1   0:28.72 mpd

mpd consumes 97% of CPU, but I was using alsaequal with MPD on Voyage 0.6.5
with no problem. I have seen the CPU utilization before, it was in the range
of 30-50%. I am not sure what caused this usage?


This is while playing mp3 without alsaequal

 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 4697 mpd       20   0 72148  13m 6148 S 10.5  5.7   0:04.57 mpd

and this one is for a flac without alsaequal

 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 4697 mpd       20   0 72148  13m 6252 S  8.2  5.8   0:12.72 mpd

Please help
