Pre-existing ALSA volume not used when opening new playback connections

[benosteen]

When opening a new connection, the card resets back to its default volume. Eg lower the volume, and then start a process to playback sound - it will play at its default level, until volume is altered, causing a quick change in output volume.

Is this because the hw doesn't persist a value for volume/attentuation between playback connections?

If so, the driver should probably persist a value during its runtime and reapply that to newly opened pcm stream connections before playback.

A recent patch should fix this issue which can be obtained through rpi-update.

Thanks for the update!

Unfortunately I am not getting any sound at all now (except for the clicking when playback starts). I checked the volume in alsamixer but it seems like I can not set it anymore. The volume bar immediately drops to zero as soon as I release the up- or pageup-key.

Any ideas?

Is it muted? (press m in alsamixer to toggle mute).

Can you confirm exactly what you type in from boot to see the problem.

It was muted, lol. Alsamixer even displayed that but I thought it would automatically unmute when increasing volume - my fault. Thanks for the tip!

Volume settings are now kept correctly, even after reboot - nice! :)

Closing as we believe this is fixed. Please reopen if there are still problems.
