LANAUDIO

Troubleshooting LANAUDIO (AES67 / Livewire)

"Nothing received" :

- UDP port ?

- if VLAN used : is same VLAN ?

- Switch IGMP snooping enable

Clocking problem

(audio clics and many "samples added/removed/overrun" in logs) :

- Check Synchro Reference Clock

- Check Synchro Status : must be stable "LOCKED"

- if VLAN used : is same VLAN for clock ?

- Switch QOS

- Switch IGMP snooping enable

- If SOUND4 is always Clock Master, better configure "Ref Clock internal" to use the clean low drift quartz (if not, may be too far from true 27MHz, and sync may not be possible)

Latency Problem

(audio clics and few "samples added/removed/overrun" in logs) :

- Switch QOS

- increase Buffer in Profile

Audio Packet Loss

- Check Audio Channel Status : must be stable "Stream OK"

- Switch QOS

- Switch IGMP snooping enable : board should not receive other audio streams than the ones configured. Check AES67/LIVEWIRE logs for "Dropped packets" with the faulty IP in hexa.
