Hi Clemens,
As I told we support synchronous multiroom audio, where in one speaker(master) streams the audio to others nodes(slave) over the network. Master speaker future timestamps the audio and re-transmits to all other nodes based on a common reference clock maintained. Our stack implements the logic to present the audio synchronously to ALSA monitoring the stamped time.We are not using snd_pcm_link().
We use MT-7620 SOC from Mediatek.
Thanks, Anoop ________________________________________ From: Clemens Ladisch clemens@ladisch.de Sent: 17 April 2015 14:37 To: Anoop Rajan; alsa-devel@alsa-project.org Subject: Re: [alsa-devel] Support for Synchronous Audio

How? With snd_pcm_link()?
What hardware are you using?
