Hello, audio on (real) n900 device does not working with 3.19 kernel. Here is relevant dmesg output: [ 5.687438] omap_i2c 48070000.i2c: bus 1 rev3.3 at 2200 kHz [ 5.696166] tpa6130a2 2-0060: Write failed [ 5.696228] tpa6130a2 2-0060: Failed to initialize chip [ 5.696380] tpa6130a2: probe of 2-0060 failed with error -121 [ 5.697937] omap_i2c 48072000.i2c: bus 2 rev3.3 at 100 kHz [ 5.700256] omap_i2c 48060000.i2c: bus 3 rev3.3 at 400 kHz [ 6.289154] rx51-audio n900-audio: Failed to add TPA6130A2 controls [ 6.295715] rx51-audio n900-audio: ASoC: failed to init TLV320AIC34: -19 [ 6.302459] rx51-audio n900-audio: ASoC: failed to instantiate card -19 [ 6.309173] gpiod_unexport: invalid GPIO [ 6.315612] rx51-audio n900-audio: snd_soc_register_card failed (-19) [ 6.397949] ALSA device list: [ 6.404876] No soundcards found. Any idea why tpa6130a2 fails to initialize?
