Excellent stuff. Thank you. The dmesg spw below is from your bone70 installation (?). Let me try and get that bone50 set up to work first.

If I disable (via capemgr) loading of BB-BONE-LCD4-01 with LCD connected then audio works - running dmesg after trying to run aplay with and without BB-BONE-LCD4-01 loaded shows two different results.

Running same test on 3.8.13-bone50 shows no such error. Note specifically error message regarding pinctrl-single 44e10800.pinmux with LCD4 loaded. Is this a red herring or indication of conflict?

My setup works flawless using kernel 3.8.13-bone50 but after updating to use 3.8.13-bone70 there seems to be an issue when LCD is connected. "aplay -l" shows audio device and running "aplay mytunes.wav" just makes a single click sound and nothing more (no music). If I disconnect the LCD then aplay works just fine. On prior kernel I did modify BB-BONE-AUDI-02 as the dts file specified exclusive gpio1_18 and gpio1_19 use (and as far I recall, these pins weren't even used) causing conflict with LCD Cape overlay - until updating kernal to bone70. dts snippet: exclusive-use = /* the pin header uses */ "P9.31", /* mcasp0: mcasp0_aclkx */ "P9.29", /* mcasp0: mcasp0_fsx */ "P9.28", /* mcasp0: mcasp0_axr2 */ "P9.25", /* mcasp0: mcasp0_ahclkx */ /* the hardware ip uses */ /*"gpio1_18", "gpio1_19",*/ "mcasp0"; root@beaglebone:~# cat /sys/devices/bone_capemgr.9/slots 0: 54:PF--- 1: 55:PF--- 2: 56:PF--- 3: 57:P---L 4D 4.3 LCD CAPE- 4DCAPE-43T ,00A1,4D SYSTEMS ,BB-BONE-LCD4-01 4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G 5: ff:P-O-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI 8: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-BONE-AUDI-03 -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
