hello i've a mac, OS uploaded to Maverick 10.9 (since the problems began), using singularity viewer everything seems all right, voice is enabled, i see my voice vawes and others can hear my voice but i can't hear them, not either in voice echo canyon. Simply no sounds from any other person. Privat call the same, nothing. i can hear environment sounds and music firewall is checked on allowing voice for singularity what else can i do? thanks PS the suggestion of reducing the bandwith is not working. Now maximum bandwith is 1940 and texture bandwith is 1440
