Re: [linux-sunxi] [PATCH 3.4] sunxi-hdmiaudio: enable low sample-rate HDMI audi
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 :-) On Tuesday, 28 January 2014 06:39:30 UTC, Rudi wrote: Am 27.01.2014 21:54, schrieb Phil Scull: Low sample rate audio was not playing on patrickhwood/linux-sunxi/tree/pat-3.4.75-ct over HDMI. 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.

[linux-sunxi] Re: [PATCH 3.4 00/11] sunxi-disp: hotplug + dpms support
Hans,
I still have trouble getting the HDMI monitor to come out of suspend
running linaro on CT.
Removing the lines that switch the clock off and back on again seems to
sort the problem. There is probably a deeper underlying issue tho.
Interested if you have any thoughts.
Kind regards,
Phil

This patchset combines the best of Michal Suchanek's, Floris Bos' and my
patches to fix various issues with hotplugging hdmi and adds dpms support.
After this the only remaining known issue is the following
1) If EDID is used, and no EDID is found on bootup so the fallback mode is
selected; and
2) A hdmi/dvi monitor gets plugged in, and its EDID does not advertise
the fallback mode; and
3) X is running
Then the fbcon code will change the mode underneath X to a supported mode,
and
X will show a garbled display. This can be worked around by switching to a
text VC and restarting X. This is more of an Xorg bug then a bug of the
sunxi
fb driver.

Hans

[linux-sunxi] sunxi 3.4: stuttering video playback
Video playback in linaro using cedar and libhybris stutters and sometimes the
frame rate drops very low.
There may be an issue in disp_video.c as the included changes sort the issue
for me.
My possibly flawed reasoning goes something like...
Its not a good idea to update display_cnt in Hal_Set_Frame called during
blanking and BSP_disp_video_set_fb which is called from an IOCTL. The value is
incremented in Hal_Set_Frame and may have been updated (to 0) by a call to
BSP_disp_video_set_fb. The result is calls to ioctl(fd,
DISP_CMD_VIDEO_GET_FRAME_ID, args) never returning the updated frame number
(this I have observed).
Hope this is of some help.
Any thoughts appreciated.
Kind regards,
Phil
