[alsa-devel] [PATCH 0/2] rt5651: Enable jack detection
by Carlo Caione 20 Oct '17

20 Oct '17

From: Carlo Caione <carlo(a)endlessm.com> Small set of patches to enable jack detection for the rt5651 codec. Please note that: - The jack detection is restricted to the JD1_1 pin only (the only hardware I have uses this pin for jack detection) - AFAICT (reading the rt5651 datasheet) there is no way to detect runtime the type of the jack inserted as done for the others rt56* codecs, so in the driver I always assume that we are dealing with an headset.

[alsa-devel] [PATCH] ALSA: hda: Avoid racy recreation of widget kobjects
by Takashi Iwai 19 Oct '17

19 Oct '17

The refresh of HD-audio widget sysfs kobjects via snd_hdac_refresh_widget_sysfs() is slightly racy. The driver recreates the whole tree from scratch after deleting the whole. When CONFIG_DEBUG_KOBJECT_RELEASE option is used, kobject release doesn't happen immediately but delayed, while the re-creation of the same named kobject happens soon after invoking kobject_put(). This may end up with the conflicts of duplicated kobjects, as found in the bug report below. In this patch, we take another approach to refresh the tree: instead of recreating the whole tree, just add the new nodes and delete the non-existing nodes. Since the refresh happens only once at initialization, no longer race would happen. Along with the code change, merge snd_hdac_refresh_widget_sysfs() with the existing snd_hdac_refresh_widgets() with an additional bool flag for simplifying the code.

[alsa-devel] [BUG] aplay doesn't honor `-t raw` when WAVE header is detected on input
by Nutchanon Wetchasit 19 Oct '17

19 Oct '17

Hello, I ran into a problem on how alsa-utils's aplay command handles `-t` option when I was trying to play a PCM WAVE file in loop, using following command: ( while true; do cat audio.wav; done ) | aplay -t raw -f S16_LE -r 44100 -c 2 An "audio.wav" can be any 44100 Hz 16-bit stereo PCM WAVE file, and `-t raw` was specially specified to make aplay reject length information in the header. However, once the command is run, first line of the output would read: Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Which shows that aplay still read the input as WAVE format, despite the `-t raw` option being explicitly specified. And you would notice that the audio *does not loop*. Instead, it will play just once, followed by silence. However, if WAVE header was stripped out (or corrupted), aplay would now treat the input as raw audio stream, and play a continuously repeated sound as expected: ( while true; do dd if=audio.wav of=/dev/stdout ibs=44 skip=1; done ) | \ aplay -t raw -f S16_LE -r 44100 -c 2 The first line of output would also show the stream as "raw data" too: Playing raw data 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo This problem exists on the latest alsa-utils 1.1.4, as well as the older 1.0.25 which came with my GNU/Linux distribution; though I'm not certain whether this is also applicable to other file format (like Sun .AU) or not. Please investigate. Regards, Nutchanon Wetchasit alsa-utils: 1.1.4 (source distribution) libasound: 1.1.4 (source distribution) System: Debian GNU/Linux 7.0 "Wheezy" i386 P.S. The "audio.wav" I used in my testing is a siren sound generated by Sox: sox -b 16 -c 2 -e signed-integer -r 44100 -n audio.wav \ synth 0.5 sine 800 gain -6 : synth 0.5 sine 600 gain -6

Hi, this is a revised patchset for addressing the incorrect TLV callback check introduced by a set_fs() removal commit. A fix for a superfluous '-' in the code is split as another fix so that it can be applied to older kernels without the rest. Other than that, only the changelog text updates since the older patch (that was embedded in the mail thread "4.13 regression: get_kctl_0dB_offset doesn't handle all possible callbacks"). thanks, Takashi === Takashi Iwai (2): ALSA: hda: Remove superfluous '-' added by printk conversion ALSA: hda - Fix incorrect TLV callback check introduced during set_fs() removal include/sound/control.h | 3 ++ sound/core/vmaster.c | 31 +++++++++++++++ sound/pci/hda/hda_codec.c | 97 +++++++++++++++++++++++++++-------------------- 3 files changed, 89 insertions(+), 42 deletions(-) -- 2.14.2
