[PATCH 00/10] ALSA: aloop: Support selection of snd_timer
by twischer＠de.adit-jv.com 26 Mar '19

26 Mar '19

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

[PATCH] ALSA: aloop: Support S24 sample formats
by twischer＠de.adit-jv.com 25 Mar '19

25 Mar '19

From: Timo Wischer <twischer(a)de.adit-jv.com> Currently snd_aloop supports only S16 and S32 audio sample formats. With this patch the S24 formats are also supported.

[PATCH] [-, JACK, plugin, 1/1] configure: use $prefix/etc instead of /etc
by Alex Ivanov 20 Mar '19

20 Mar '19

Use $sysconfdir as prefix for ALSA_LCONF_DIR by default. Otherwise install fails on non-FHS distros.

[PATCH] [-, JACK, plugin, 1/1] jack: use correct port names in 50-jack.conf
by Alex Ivanov 20 Mar '19

20 Mar '19

Change port names in 50-jack.conf from "alsa_pcm" to "system". JACK1 v0.125.0 still provides alsa_pcm:playback_* and alsa_pcm:capture_* port names, but only as aliases: $ jack_lsp -A system:capture_1 alsa_pcm:capture_1 system:capture_2 alsa_pcm:capture_2 system:playback_1 alsa_pcm:playback_1 system:playback_2 alsa_pcm:playback_2 JACK2 v1.9.12 doesn't support alsa_pcm:playback_* and alsa_pcm:capture_* aliases anymore, so 50-jack.conf will fail for JACK2 users: $ jack_lsp -A system:capture_1 alsa_pcm:hw:0:out1 system:capture_2 alsa_pcm:hw:0:out2 system:playback_1 alsa_pcm:hw:0:in1 system:playback_2 alsa_pcm:hw:0:in2 As you see in both cases system:playback_* and system:capture_* are correct port names.
