Subject: [PATCH] hw/audio/hda: avoid unnecessary re-open stream on
|
||
|
|
reconfiguration

|
Closing and opening a stream too quickly during reconfiguration create
|
||
|
|
issues with Spice.
|
||
|
|
|
||
|
|
Note: the issue with Spice has been there before and still is. When the
|
||
|
|
audio stream is recreated, for example when using
|
||
|
|
`out.mixing-engine=false`.
