[alsa-devel] [PATCH] ALSA: usb-audio: fix PCM device order
by Alexander Tsoy 27 Jul '19

27 Jul '19

Some cards have alternate setting with non-PCM format as the first altsetting in the interface descriptors. This confuses userspace, since alsa-lib uses device 0 by default. So lets parse interfaces in two steps: 1. Parse altsettings with PCM formats. 2. Parse altsettings with non-PCM formats. This fixes at least following cards: - Audinst HUD-mx2 - Audinst HUD-mini Signed-off-by: Alexander Tsoy <alexander(a)tsoy.me> --- sound/usb/stream.c | 27 ++++++++++++++++++++++++++- 1 file changed, 26 insertions(+), 1 deletion(-) diff --git a/sound/usb/stream.c b/sound/usb/stream.c index 8e9548bc1f1a..b2ebeae91396 100644 --- a/sound/usb/stream.c +++ b/sound/usb/stream.c @@ -477,7 +477,8 @@ static struct uac2_output_terminal_descriptor * return NULL; } -int snd_usb_parse_audio_interface(struct snd_usb_audio *chip, int iface_no) +static int __snd_usb_parse_audio_interface(struct snd_usb_audio *chip, int iface_no, + bool *has_non_pcm, bool non_pcm) { struct usb_device *dev; struct usb_interface *iface; @@ -634,6 +635,10 @@ int snd_usb_parse_audio_interface(struct snd_usb_audio *chip, int iface_no) iface_no, altno); continue; } + if (fmt->bFormatType != UAC_FORMAT_TYPE_I) + *has_non_pcm = true; + if ((fmt->bFormatType == UAC_FORMAT_TYPE_I) == non_pcm) + continue; if (((protocol == UAC_VERSION_1) && (fmt->bLength < 8)) || ((protocol == UAC_VERSION_2) && (fmt->bLength < 6))) { dev_err(&dev->dev, @@ -740,3 +745,23 @@ int snd_usb_parse_audio_interface(struct snd_usb_audio *chip, int iface_no) return 0; } +int snd_usb_parse_audio_interface(struct snd_usb_audio *chip, int iface_no) +{ + int err; + bool has_non_pcm = false; + + /* parse PCM formats */ + err = __snd_usb_parse_audio_interface(chip, iface_no, &has_non_pcm, false); + if (err < 0) + return err; + + if (has_non_pcm) { + /* parse non-PCM formats */ + err = __snd_usb_parse_audio_interface(chip, iface_no, &has_non_pcm, true); + if (err < 0) + return err; + } + + return 0; +} + -- 2.13.0

[alsa-devel] Plugged in headphones ignored
by Paul Menzel 27 Jul '19

27 Jul '19

Dear Linux folks, On a Dell OptiPlex 5040 with Linux 5.2-rc6 plugging in a head phone into the front case connector, it is detected just fine and Xfce shows a notification. Then logging out, turning off the monitor connected over DisplayPort at the end of the day, and turning the monitor back on the next morning, logging in, the state is forgotten. I need to unplug the head phone and plug it back in. Please find the output alsa-config.sh for the non-working (1) and replugged (2) situations attached. Is that a Linux kernel problem, or a user space issue? Kind regards, Paul

[alsa-devel] [PATCH v2] ASoC: SOF: Intel: hda: Make hdac_device device-managed
by Ranjani Sridharan 22 Jul '19

22 Jul '19

snd_hdac_ext_bus_device_exit() has been recently modified to no longer free the hdac device. SOF allocates memory for hdac_device and hda_hda_priv with kzalloc. Make them device-managed instead so that they will be freed when the SOF driver is unloaded. Because of the above change, hda_codec is device-managed and it will be freed when the ASoC device is removed. Freeing the codec in snd_hda_codec_dev_release() leads to kernel panic while unloading and reloading the ASoC driver. So, avoid freeing the hda_codec for ASoC driver. This is done in the same patch to avoid bisect failure.

[alsa-devel] [PATCH v2 0/6] VAG power control improvement for sgtl5000 codec
by Oleksandr Suvorov 11 Jul '19

11 Jul '19

VAG power control is improved to fit the manual. This fixes as minimum one bug: if customer muxes Headphone to Line-In right after boot w/o playing any sound, the VAG power remains off that leads to poor sound quality from line-in. I.e. after boot: - Connect sound source to Line-In jack; - Connect headphone to HP jack; - Run following commands: $ amixer set 'Headphone' 80% $ amixer set 'Headphone Mux' LINE_IN Also this series includes fixes of non-important bugs in sgtl5000 codec driver. Fix patch formatting in patchset v2.

From: Timo Wischer <twischer(a)de.adit-jv.com> Since ARMv7 hardware cache coherence is supported. "The SCU maintains coherency between the individual data caches in the Cortex-A5 MPCore processor using a variation of the MOESI protocol" [1]. Therefore this patch enables the MMAP access to the status and control structures. This avoids HWSYYNC ioctl calls and therefore lowers the CPU usage.

[alsa-devel] [PATCH 0/7] Add HDMI audio support on RK3288 veyron board
by Cheng-Yi Chiang 10 Jul '19

10 Jul '19

This patch series is to support HDMI audio on RK3288 veyron board. To support jack reporting, there are two old patches: video: add HDMI state notifier support <https://lore.kernel.org/linux-media/20161213150813.37966-2-hverkuil@xs4all.…> ASoC: hdmi-codec: use HDMI state notifier to add jack support <https://patchwork.kernel.org/patch/9430355/> They are modified to pass checkpatch checking based on latest ASoC tree https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next branch. With these two patches at hand, hdmi-notifier support is then added to dw-hdmi driver so the plug/unplug event can be passed to codec driver. The rest patches are about machine driver rockchip_max98090. A HDMI DAI link is added for HDMI playback so there will be two devices on this sound card. One for max98090 and one for HDMI. The HDMI node is passed from DTS so machine driver can set the correct hdmi-notifier on codec driver.
