alsa-project/alsa-utils issue #37 was opened from dbaluta: With latest alsa-lib and alsa-utils sources I cannot compile alsatplg utility. Steps followed: # Compile alsa-lib 1. ./gitcompile --prefix=$HOME/work/sof_dir/alsa-lib-bins/ 2. make install #custom instalation to be later used by alsa-utils. # Compile alsa-utils 1. /gitcompile --with-alsa-inc-prefix=$HOME/work/sof_dir/alsa-lib-bins/include/ --with-alsa-prefix=$HOME/work/sof_dir/alsa-lib-bins/lib 2. I get the following errors: ``` -ldl -lpthread topology.o: In function `load_topology': /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:135: undefined reference to `snd_tplg_create' /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:141: undefined reference to `snd_tplg_load' /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:145: undefined reference to `snd_tplg_free' topology.o: In function `version': /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:63: undefined reference to `snd_tplg_version' topology.o: In function `dump': /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:218: undefined reference to `snd_tplg_save' /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:219: undefined reference to `snd_tplg_free' topology.o: In function `compile': /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:245: undefined reference to `snd_tplg_build_bin' /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:246: undefined reference to `snd_tplg_free' topology.o: In function `decode': /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:268: undefined reference to `snd_tplg_create' /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:273: undefined reference to `snd_tplg_decode' /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:281: undefined reference to `snd_tplg_save' /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:282: undefined reference to `snd_tplg_free' /home/nxf25322/work/sof_dir/alsa-utils/topology/topology.c:276: undefined reference to `snd_tplg_free' collect2: error: ld returned 1 exit status Makefile:433: recipe for target 'alsatplg' failed ``` Similar with https://github.com/alsa-project/alsa-utils/issues/33 Issue URL : https://github.com/alsa-project/alsa-utils/issues/37 Repository URL: https://github.com/alsa-project/alsa-utils

M-Audio Fast Track Ultra S/PDIF clock source
by George Marques 07 Apr '20

07 Apr '20

Hello, I have my trusty old FTU audio interface and I've been super happy of how it works well on Linux with ALSA. Today I finally found some use for the S/PDIF input, which would allow me to free up two analog inputs in my setup. However, I found out it's not possible to change the clock source using ALSA, so I cannot use the S/PDIF input on Linux. This issue was raised by Felix Homann back in 2011: https://www.alsa-project.org/pipermail/alsa-devel/2011-June/040846.html but I couldn't find any new development, even though other issues were fixed. On Windows the proprietary driver naturally has an option for that, which allowed me to verify that the input is in fact working correctly. Changing on Windows and then rebooting into Linux does not work, so either this is not persisted or something on Linux is unknowingly changing it back. I actually want to help add this option to the driver, so I can use it myself but also make it available to others who still rely on this interface. My questions are: 1) Was there any progress in this regard? Most of work has been done around 2012 for what I could find, nothing newer, so can I assume no work was done after the concern was raised? 2) If I were to develop this option, where could I start? I can get myself around with C, but I have no idea how to debug and test my patches, nor how to find the exact control. I know it's an old card, but it works very well for me so I have no excuse to just replace it at this point. I hope someone can help me.

[PATCH] ASoC: cs4270: pull reset GPIO low then high
by Mike Willard 07 Apr '20

07 Apr '20

Pull the RST line low then high when initializing the driver, in order to force a reset of the chip. Previously, the line was not pulled low, which could result in the chip registers not resetting to their default values on boot.

[PATCH v2 00/12] [RESEND] ASoC: SOF DSP virtualisation
by Guennadi Liakhovetski 07 Apr '20

07 Apr '20

This patch series extends the SOF driver to add support for DSP virtualisation to ASoC. It is built on top of VirtIO, contains a guest driver and a vhost in-kernel guest driver. This version supports a single playback and a single capture interface on the guest. The specific guest audio topology is supplied by the host from a file, specified on the QEMU command line. This solution is designed to use advanced DSP functionality, available on the host. In case no DSP is available on the host, a fall-back should be provided in the future to the pure audio virtualisation standard, currently developed by OASIS. Extensive documentation is available at [1]. I'd like to have at least a tentative approval on this series to send vhost patches 3 and 9 to virtualisation lists / maintainers for review and eventual merging. v2: one patch merged, one patch resubmitted separately, otherwise no changes.

alsa-gobject: Add shared library to operate ALSA hwdep character device
by GitHub pull_request - opened 07 Apr '20

07 Apr '20

alsa-project/alsa-gobject pull request #15 was opened from takaswie: This patchset is to add a new library, libalsahwdep, to operate ALSA hwdep character device. ALSA hwdep interface is designed to execute driver-dependent code from user space application. Therefore there're a few common operations. Furthermore, some of the operations are just for ALSA snd-usb-usx2y driver for TASCAM US-122, US-224 and US-428, as of Linux kernel v5.6. The library doesn't support the device-dependent operations. The library has 4 global APIS. ALSAHwdep.get_device_id_list() returns the list of numerical IDs of hwdep device in a card. ALSAHwdep.get_hwdep_sysname() and ALSAHwdep.get_hwdep_devnode() returns sysname and devnode for the card and hwdep device. ALSAHwdep.get_device_info() returns ALSAHwdep.DeviceInfo GObject-derived object which represents the information of hwdep device of the card. The object has some properties, one of which is a enumeration in ALSAHwdep.IfaceType to represent the type of hwdep device.

[PATCH] ASoC: rt5645: Add platform-data for Medion E1239T
by Hans de Goede 06 Apr '20

06 Apr '20

The Medion E1239T uses the default jack-detect mode 3, but instead of using an analog microphone it is using a DMIC on dmic-data-pin 1, like other models following Intel's Brasswell's reference design. This commit adds a DMI quirk pointing to the intel_braswell_platform_data for this model.

[PATCH] ASoC: stm32: sai: Add missing cleanup
by Julia Lawall 06 Apr '20

06 Apr '20

The commit 0d6defc7e0e4 ("ASoC: stm32: sai: manage rebind issue") converts some function calls to their non-devm equivalents. The appropriate cleanup code was added to the remove function, but not to the probe function. Add a call to snd_dmaengine_pcm_unregister to compensate for the call to snd_dmaengine_pcm_register in case of subsequent failure.
