Привет Гуру андроида
. Темы про Alwinner нету, посему напишу здесь:
Вот и издох мой весело поющий проект на Alwinner A10, не выдержал очередных моих надругательств
Пришло время собирать камни...А именно, прикупил планшет Onda v813 на Alwinner A31 (без S), дабы накатить на него цианоген все от того же CristianTroy`я (где заявленна поддержка USB Audio).
Планшет приехал. Отдельный усб ускоглазые зажали, сдул вайфай, накатил хаб, вернул вайфай, вообщем все как и ранее, но моя звучка петь отказалась:

W/AudioPolicyManagerBase(1206): checkOutputsForDevice(): No output available for device 0800

как выразился в одной из веток Трой - не катит ваша звучка под линем и все тут. WTF? ведь раньше пела!
Пробовал свою китайскую звучку снятую с машины, SB surround 5.1, какойто Asus - поведение идентичное.
Перепробовал все сборки, что были у троя и на ParanoidAndroid при воспроизведении трека звучка издала звуки из преисподни!
Продолбавшись еще пару часов я перетыкнул ее в OTG (чем черт не шутит) и звучка запела. почти нормально. НО! радость была не долгой. Громкость не регулирутеся. Орет на максимуме. Ползунок регулируешь, переоткрываешь микшер, а он снова на максимуме. Регулируешь громкость будильника - звук будильника играет на планшете, а трек играет на усб.
А теперь вопрос: как прикрутить системный регулятор громкости к звучке?
