[alsa-devel] New focusrite USB ID
by Gunter Königsmann 30 Mar '17

30 Mar '17

Dear all, The ardour-users mailing list mehtions that there is a new USB-ID to be found from focusrite: 1235:8004 is the 18i6. Source: http://lists.ardour.org/pipermail/ardour-users-ardour.org/2017-March/028365… As I don't have this specific hardware I cannot help with the testing but I thought I can at least report this thanking the alsa programmers as the focusrite scarlett I have at home works like a charm on linux. Kind regards, Gunter.

[alsa-devel] No Jack sound on Lenovo dock with a T470 connected
by dmummenschanz＠web.de 30 Mar '17

30 Mar '17

Hello, I'm unable to get sound via the jack headphone connection on my lenovo dock when a t470 is connected. Some years ago I've experienced a similar issue with a t440p connected to the same docking station. Back than a patch helped to activate the jack sound: [codec] 0x10ec0292 0x17aa220e 0 [pincfg] 0x16 0x21211010 0x19 0x21a11010 So I've tried to match codec and pincfg to my t470 without success

[alsa-devel] [PATCH] ALSA: hda - set intel audio clock to a properly value
by libin.yang＠intel.com 30 Mar '17

30 Mar '17

From: Libin Yang <libin.yang(a)intel.com> On some Intel platforms, the audio clock may not be set correctly with initial setting. This will cause the audio playback/capture rates wrong. This patch checks the audio clock setting and will set it to a properly value if it is not set correct.

[alsa-devel] [PATCH] sound: oxygen: simply setting of the shortname for Xonar DG cards
by Clemens Ladisch 29 Mar '17

29 Mar '17

We don't need to manually set the card name; with an entry in the names[] array, this happens automatically.

[alsa-devel] dmix, snd_pcm_drain(), SND_PCM_NONBLOCK - bug?
by Max Kellermann 29 Mar '17

29 Mar '17

Hi, I have received a bug report for the Music Player Daemon which complains about a freezing MPD process, after I switched MPD's ALSA output to non-blocking mode: https://bugs.musicpd.org/view.php?id=4662 This happens when snd_pcm_drain() is used on a dmix PCM which is in SND_PCM_NONBLOCK mode. snd_pcm_drain() will be called repeatedly, because ALSA's file descriptor is always ready. According to my research, the bug is in __snd_pcm_dmix_drain(). This function always returns -EAGAIN when SND_PCM_NONBLOCK is set: if (pcm->mode & SND_PCM_NONBLOCK) return -EAGAIN; This comes very early in the function, before any other relevant checks. It can never finish that way, and calling it again at any time will never do anything. Thus, snd_pcm_drain() appears to be broken in non-blocking mode. Or am I misunderstanding how snd_pcm_drain() is supposed to be used in non-blocking mode? Max

[alsa-devel] [PATCH] ASoC: WM8962: Let codec driver enable/disable its MCLK
by Daniel Baluta 29 Mar '17

29 Mar '17

From: Nicolin Chen <b42378(a)freescale.com> WM8962 needs its MCLK when powerup in wm8962_resume(). Thus it's better to control the MCLK in codec driver. Thus remove the clock enable in machine dirver accordingly. While at it, get rid of imx_wm8962_remove function since it is now empty.

[alsa-devel] [PATCH v3 0/2] imx-wm8962: Let codec driver enable/disable its MCLK
by Daniel Baluta 29 Mar '17

29 Mar '17

This is a small cleanup patch series which removes MLCK enable/disable from imx-wm8962 machine driver and lets the codec handle that. While reviewing this, Nicolin noticed that codec_clk cleanup is not correct so the second patch fixes this. Changes since v2: * added 2/2 patch to fix codec_clk cleanup * fixed prefix subject Daniel Baluta (2): ASoC: imx-wm8962: Let codec driver enable/disable its MCLK ASoC: imx-wm8962: Fix codec_clk cleanup sound/soc/fsl/imx-wm8962.c | 41 +++++++++-------------------------------- 1 file changed, 9 insertions(+), 32 deletions(-) -- 2.7.4
