Re: [linux-sunxi] [PATCH 3.4] sunxi-hdmiaudio: enable low sample-rate HDMI audi

2014-01-28 Thread Phil Scull
Cubietruck (A20) connected to a BenQ monitor. The driver 
advertises SNDRV_PCM_RATE_8000_192000 in sndhdmi.c which I guess is 
incorrect if HDMI does not support it + I must be very lucky :-)

  The following changes result in sound being played, which can be 
 demonstrated with 
  speaker-test. 

 On which devcie did you try ? AFAIK, the HDMI spec does not allow rates 
 below 32kHz. 
 So if that works, it's just good luck. My Yamaha AVR for example would not 
 accept 
 anything these rates. Not even on S/PDIF.
