I'm using the kernel 4 and the result is the same (can't avoid the reboot loop) Which manual mods do you mean (the ones I'm making to the settnigs file)? I've been doing a little more digging. I can't get the DAC to play from ssh using aplay, for example: # aplay -D hw:1,0 /tmp/track02.wav Playing WAVE '/tmp/track02.wav' : Signed 24 bit Little Endian in 3bytes, Rate 44100 Hz, Stereo aplay: set_params:1022: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S24_3LE SUBFORMAT: STD SAMPLE_BITS: 24 FRAME_BITS: 48 CHANNELS: 2 RATE: 44100 PERIOD_TIME: (125011 125012) PERIOD_SIZE: 5513 PERIOD_BYTES: 33078 PERIODS: (3 4) BUFFER_TIME: 500000 BUFFER_SIZE: 22050 BUFFER_BYTES: 132300 TICK_TIME: 0 presumably this needs to work properly? Doing the same thing from my laptop (with the same audio track) it works ok: jacko@mpc540:~$ aplay -D hw:1,0 ./Desktop/track02.wav -v Playing WAVE './Desktop/track02.wav' : Signed 24 bit Little Endian in 3bytes, Rate 44100 Hz, Stereo Hardware PCM card 1 'ARCAM DAC' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : RW_INTERLEAVED format : S24_3LE subformat : STD channels : 2 rate : 44100 exact rate : 44100 (44100/1) msbits : 24 buffer_size : 22050 period_size : 5513 period_time : 125011 tstamp_mode : NONE period_step : 1 avail_min : 5513 period_event : 0 start_threshold : 22050 stop_threshold : 22050 silence_threshold: 0 silence_size : 0 boundary : 6206523236469964800 appl_ptr : 0 hw_ptr : 0 jacko@mpc540:~$ While playing on the laptop the output of cat /proc/asound/card1/stream0 gives: ARCAM ARCAM DAC at usb-0000:00:1d.0-1, full speed : USB Audio Playback: Status: Running Interface = 1 Altset = 1 URBs = 3 [ 8 8 8 ] Packet Size = 585 Momentary freq = 44104 Hz (0x2c.1a98) Feedback Format = 10.14 Interface 1 Altset 1 Format: S24_3LE Channels: 2 Endpoint: 1 OUT (ASYNC) Rates: 32000, 44100, 48000, 88200, 96000 is this down to the version of alsa? or are you bypassing alsa completely? I was trying to get it to work by fiddling with the aplay command line options. -- jackocleebrown ------------------------------------------------------------------------ jackocleebrown's Profile: http://forums.slimdevices.com/member.php?userid=10623 View this thread: http://forums.slimdevices.com/showthread.php?t=93310 _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
