How is your C2 powered?
- micro USB
- or DC input jack

Is the OTG power enable jumper* installed?

What happens if you disconnect and connect the touch USB while your C2 is running?
Does the touch work after doing that?

And if possible please post the output from
"/proc/asound/card*/pcm*p/sub*/hw_params"

Code: Select all
cat /proc/asound/card*/pcm*p/sub*/hw_params

Replace the * with your numbers.

Hi Frank,

I use DC Jack to power C2 up.
Both HDMI and USB on C2 are connected to WaveShare.
OTG jumper have not removed.
I have try to unplug and plug again USB cable from display, touch screen function still not works.

You have to play a song while trying to read the hardware parameters.

I lost the overview in this thread, so please open a new one with your specific issue!

Hi,

Do you know how to setup 1080p mode to connect the TV? Because I connected TV via HDMI cable but no signal. Thanks!

You have to edit the file "/boot/boot.ini" on your sd card.
This can be done on your PC (sd card reader) or remotely on your C2.
If doing it remotely (ssh) you first have to switch the filesystem to read write!

Code: Select all: set_rw

Code: Select all: ODROIDC2-UBOOT-CONFIG # Possible screen resolutions # Uncomment only a single Line! The line with setenv written. # At least one mode must be selected. # 480 Lines (720x480) # setenv m "480i60hz" # Interlaced 60Hz # setenv m "480i_rpt" # Interlaced for Rear Projection Televisions 60Hz # setenv m "480p60hz" # 480 Progressive 60Hz # setenv m "480p_rpt" # 480 Progressive for Rear Projection Televisions 60Hz # 576 Lines (720x576) # setenv m "576i50hz" # Interlaced 50Hz # setenv m "576i_rpt" # Interlaced for Rear Projection Televisions 50Hz # setenv m "576p50hz" # Progressive 50Hz # setenv m "576p_rpt" # Progressive for Rear Projection Televisions 50Hz # 720 Lines (1280x720) # setenv m "720p50hz" # 50Hz # setenv m "720p60hz" # 60Hz # 1080 Lines (1920x1080) # setenv m "1080i60hz" # Interlaced 60Hz # setenv m "1080p60hz" # Progressive 60Hz # setenv m "1080i50hz" # Interlaced 50Hz # setenv m "1080p50hz" # Progressive 50Hz # setenv m "1080p24hz" # Progressive 24Hz # 4K (3840x2160) # setenv m "2160p30hz" # Progressive 30Hz # setenv m "2160p25hz" # Progressive 25Hz # setenv m "2160p24hz" # Progressive 24Hz # setenv m "smpte24hz" # Progressive 24Hz SMPTE # setenv m "2160p50hz" # Progressive 50Hz # setenv m "2160p60hz" # Progressive 60Hz # setenv m "2160p50hz420" # Progressive 50Hz with YCbCr 4:2:0 (Requires TV/Monitor that supports it) # setenv m "2160p60hz420" # Progressive 60Hz with YCbCr 4:2:0 (Requires TV/Monitor that supports it) ### VESA modes ### # setenv m "640x480p60hz" setenv m "800x480p60hz" # setenv m "800x600p60hz" # setenv m "1024x600p60hz" # setenv m "1024x768p60hz" # setenv m "1280x800p60hz" # setenv m "1280x1024p60hz" # setenv m "1360x768p60hz" # setenv m "1366x768p60hz" # setenv m "1440x900p60hz" # setenv m "1600x900p60hz" # setenv m "1680x1050p60hz" # setenv m "1920x1200p60hz" ........

You have to remove the hash (#) from one of these lines

# 1080 Lines (1920x1080)
# setenv m "1080i60hz" # Interlaced 60Hz
# setenv m "1080p60hz" # Progressive 60Hz

# setenv m "1080p24hz" # Progressive 24Hz

and disable 800x480

### VESA modes ###
# setenv m "640x480p60hz"
# setenv m "800x480p60hz"
# setenv m "800x600p60hz"
# setenv m "1024x600p60hz"
# setenv m "1024x768p60hz"
# setenv m "1280x800p60hz"
# setenv m "1280x1024p60hz"
# setenv m "1360x768p60hz"
# setenv m "1366x768p60hz"
# setenv m "1440x900p60hz"
# setenv m "1600x900p60hz"
# setenv m "1680x1050p60hz"
# setenv m "1920x1200p60hz"

You also have to change the zoom factor in midori by editing this file:
/home/root/.config/midori/config

[settings]
default-encoding==UTF-8
enforce-96-dpi=true
enable-developer-extras=true
enable-site-specific-quirks=true
enable-javascript=true

last-window-height=480
last-panel-position=523
last-panel-page=5
location-entry-search=

find-while-typing=true
zoom-level=0.7
middle-click-opens-selection=false
homepage=http://localhost
tabhome=about:dial
download-folder=/home/army
http-proxy=127.0.0.1:8118
maximum-cache-size=50
maximum-history-age=0
load-on-startup=MIDORI_STARTUP_HOMEPAGE
proxy-type=MIDORI_PROXY_NONE
user-agent=Mozilla/5.0 (X11; Linux) AppleWebKit/538.15 (KHTML, like Gecko) Chrome/18.0.1025.133 Safari/538.15 Midori/0.5
user-stylesheet-uri=file:///root/.local/share/midori/styles/local-styles.css

[extensions]
libaddons.so=true

I would try to set it to 1.

@hondagx35: My issue is C2 played perfectly with 24/192 only and the rest (16/44.1 ; dsd64 ; dsd128) the sounds are very distorted and noisy so you advised me to get the signal when playing "cat /proc/asound/card*/pcm*p/sub*/hw_params" that I got it from the playing files herewith for all (16/44.1 ; dsd64 ; dsd128).

It is strange that 24/192 played perfectly but output from the same command is also the same.
My DAC is the USD DAC SMSL M8 with the external power supply fed by C2 via USB port.

HI Michael,
Would you mind to let me know how you connect the runeaudio from iPad? Through Web? Or other MPD app?
For your Chinese / Japanese song, is it in WAV file formation? (For me, the problem just happen on WAV file format with Chinese tag).

About your display issue on attached display, I don't know whether is it the same issue as mentioned in great-compatibility-on-double-byte-character-display-on-0-4-t3347.html#p12914.

Best Rgds.,

Hi acml,

I connect runeaudio from iPad mini (IOS 9.3.1) with Safari, URL: runeaudio.local

All my Chinese / Japanese song are FLAC for PCM, DSF for DSD.

As you can see at post you referred, I have no issue on display Chinese and Japanese at my iPad mini
although the test was held on RP3 with 0.4 beta.

Cover Art on the RuneAudio UI works?
You only have problems with MPaD , right?

I know that folder /covers doesn't exist. I've 'mkdir' that by my self. But nginx seems compiled with '--without-http_autoindex_module' flag so i cannot share that folder to MPaD/MPoD. Do i need recompile nginx for my needs?

@hondagx35: I tested your advised command "cat /proc/asound/card*/pcm*p/sub*/hw_params" for both devices Raspberry Pi 2 (Pi2) and Odroid C2 (C2) on playing the same music files output via USB to the same USB DAC SMSL M8 that you could see the figures as follows:

Note: I made this comparison since I have no issue at all when playing on Pi2. Pi2 played perfectly.

1) Playing 16/44.1
Pi2:

Code: Select all: [root@runeaudio ~]# cat /proc/asound/card*/pcm*p/sub*/hw_params access: RW_INTERLEAVED format: S24_3LE subformat: STD channels: 2 rate: 44100 (44100/1) period_size: 5513 buffer_size: 22050 closed closed closed closed closed closed closed closed closed closed

C2:

Code: Select all: root@runeaudio(ro):~# cat /proc/asound/card*/pcm*p/sub*/hw_params closed access: RW_INTERLEAVED format: S24_3LE subformat: STD channels: 2 rate: 44100 (44100/1) period_size: 5513 buffer_size: 22050

2) Playing 24/192
Pi2:

Code: Select all: [root@runeaudio ~]# cat /proc/asound/card*/pcm*p/sub*/hw_params access: RW_INTERLEAVED format: S24_3LE subformat: STD channels: 2 rate: 192000 (192000/1) period_size: 24000 buffer_size: 96000 closed closed closed closed closed closed closed closed closed closed

C2:

3) Playing DSD64
Pi2:

Code: Select all: [root@runeaudio ~]# cat /proc/asound/card*/pcm*p/sub*/hw_params access: RW_INTERLEAVED format: S24_3LE subformat: STD channels: 2 rate: 176400 (176400/1) period_size: 22050 buffer_size: 88200 closed closed closed closed closed closed closed closed closed closed

C2:

Code: Select all: root@runeaudio(ro):~# cat /proc/asound/card*/pcm*p/sub*/hw_params closed access: RW_INTERLEAVED format: DSD_U32_BE subformat: STD channels: 2 rate: 88200 (88200/1) period_size: 11025 buffer_size: 44100

4) Playing DSD128
Pi2:

Code: Select all: [root@runeaudio ~]# cat /proc/asound/card*/pcm*p/sub*/hw_params access: RW_INTERLEAVED format: S24_3LE subformat: STD channels: 2 rate: 352800 (352800/1) period_size: 43691 buffer_size: 174762 closed closed closed closed closed closed closed closed closed closed

C2:

Code: Select all: root@runeaudio(ro):~# cat /proc/asound/card*/pcm*p/sub*/hw_params closed access: RW_INTERLEAVED format: DSD_U32_BE subformat: STD channels: 2 rate: 176400 (176400/1) period_size: 22050 buffer_size: 88200

Hope this helps.
