So if anyone is interested, the cause of this issue is the following "fix" :
http://linuxtv.org/hg/v4l-dvb/rev/93e265de2a56
when reverse applying it, I got the sound track in all my mpeg devices,
and then "api mailbox timeout" message never appeared afterwards.
I can prepare a patch if you want. Who should I send it to ?
