You're probably better off on alsa-devel@: https://alsa-project.org/wiki/Mailing-lists#alsa-devel_at_alsa-project.org I have no good immediate solution to offer (I lost touch with Linux audio 5yrs ago, don't know why I'm still on this list :) ). Maybe you can even start streaming in the chip init function and track in a bool whether this is the actual stream or not. If not, then send silence (memset the buffer, so that there's no noise), and only send real data if there was a start command. Terrible hack and obviously bad for power consumption. I'm sure Takashi has better ideas on alsa-devel@. ;) -- mail: a...@thur.de http://adi.thur.de PGP/GPG: key via keyserver _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/linux-audio-dev
