Subject: [PATCH 00/10] ALSA: aloop: Support selection of snd_timer
Date: Mon, 25 Mar 2019 17:00:34 +0100 [thread overview]
Message-ID: <1553529644-5654-1-git-send-email-twischer@de.adit-jv.com> (raw)
With the following patch set any sound timer can be used as timer source
for the aloop devices if selected. It can be select by the additional
timer_source kernel module parameter:
-2 the jiffies timer will be used as done without this patch (default)
-1 the sound timer will be selected depending on the linked sound cards
(snd_pcm_link()). The sound timer of the first linked card which is not
a aloop device nor a dummy device will be used.
0..N Select the sound timer by the card number.
This patch set is required for forwarding audio data between a HW sound card
and an aloop device without the usage of an asynchronous sample rate converter.
Best regards,
Timo
