airtime in ubuntu 12.04 without pulseaudio

Good morning everybody,

I have installed airtime in ubuntu server 12.04 following the instructions from the manual in section: Automated installation
Earlier on "preparing the server" the manual suggest to remove the pulse-audio server, so i had it removed.

After enabling the the Hardware Audio Output ALSA , on the airtime-playout status i was getting:

AIRTIME_STATUS_URL             = http://localhost:80/api/status/format/json/api_key/%%api_key%%
AIRTIME_SERVER_RESPONDING      = OK
KERNEL_VERSION                 = 3.2.0-23-generic
MACHINE_ARCHITECTURE           = x86_64
TOTAL_MEMORY_MBYTES            = 3960548
TOTAL_SWAP_MBYTES              = 7631868
AIRTIME_VERSION                = 2.1.3
OS                             = Ubuntu 12.04 LTS x86_64
CPU                            = Intel(R) Pentium(R) CPU G850 @ 2.90GHz
WEB_SERVER                     = Apache/2.2.22 (Ubuntu)
PLAYOUT_ENGINE_PROCESS_ID      = 7669
PLAYOUT_ENGINE_RUNNING_SECONDS = 10
PLAYOUT_ENGINE_MEM_PERC        = 0.3%
PLAYOUT_ENGINE_CPU_PERC        = 0.0%
LIQUIDSOAP_PROCESS_ID          = FAILED


The output from both the "/var/log/airtime/pypo/pypo.log" and the "sudo -u pypo /usr/lib/airtime/pypo/bin/airtime-liquidsoap" command was similar:

2012/07/23 13:02:36 [clock.wallclock_pulse:2] Error when starting output pulse_out(liquidsoap:): Pulseaudio error: Connection refused!

After reinstalling pusleaudio everything worked ok.

-- Your installation of Airtime looks OK!



Please advise if there is another way to fix this or if it is ok to keep pulseaudio:
