Subject: [Qemu-devel] [PATCH v4 03/14] audio: add audiodev property to vnc and wav_capture
Date: Mon, 19 Aug 2019 01:06:48 +0200
Message-ID: <8cbc9e865bbf40850c14340fc0549e6ac2d5fe9c.1566168923.git.DirtY.iCE.hu@gmail.com> (raw)

Notes:
    Changes from v2:
    
    * audiodev parameter for wavcapture is now mandatory.
    * removed some unnecessary qdict_haskey calls from hmp_wavcapture
