[Enhancement] aplay: make stream pause/resume automation/script friendly
by GitHub issues - opened 07 Jul '22

07 Jul '22

alsa-project/alsa-utils issue #155 was opened from aiChaoSONG: There is an `-i` option for interactive mode, in the interactive mode, we are able to pause/resume the playback/capture stream with SPACE key, which is very good. However we have to do this in a terminal, because there is a isatty check on the stdin, this is not friendly for automation/script to test audio pause/resume feature with aplay. Is it possible to remove the isatty check, so that we can do pause/result test with a single stdin redirection? Another possible fix is that we can make use of the SIGUSR2, so that we pause/resume stream by sending signal to the aplay process. @perexg Issue URL : https://github.com/alsa-project/alsa-utils/issues/155 Repository URL: https://github.com/alsa-project/alsa-utils

How to get mixer control index from UCM
by GitHub issues - edited 07 Jul '22

07 Jul '22

alsa-project/alsa-lib issue #248 was edited from Zames-Chang: I use Corsair VOID ELITE USB Gaming Headset. However this headset have two same name control ``` $ amixer -c 1 scontrols Simple mixer control 'Auto Gain Control',0 Simple mixer control 'Headset',0 Simple mixer control 'Headset',1 ``` use command to change 'Headset',0 is actually not working. But change 'Headset',1 will work. I want write a UCM to indicate that when seeing this headset, choose the name 'Headset' with index 1 not index 0. I have seen [use-case.h](https://github.com/alsa-project/alsa-lib/blob/master/include/us… recommended names for values, but I don't find a proper name to describe control index. Is there any suggestion about how to write control index in UCM file? Issue URL : https://github.com/alsa-project/alsa-lib/issues/248 Repository URL: https://github.com/alsa-project/alsa-lib

pcm.c:3236: snd_pcm_area_copy: Assertion `src < dst || src >= dst + bytes' failed.

Anyone could tell me what's wrong with the attached code? I get a 100% reproducible crash that ends in $subject and a core dump as soon as snd_pcm_drain() is called. This is a test case to reliably demonstrate the same issue I get when using espeak-ng. It is somewhat harder to reproduce with espeak as it happens more randomly, but still highly irritating.

If that's really the case, please reword your title - Fixes-tag belongs to the tag area and should be placed before your final signed-off tag. Also, as commit message is _not_ a title and is made of sentences, it is expected to have each end with '.'. Another suggestion - nothing is "Fixed" when patch lands on the mailing list. It's just a proposal until it actually gets integrated by the maintainer. As change targets _current_ code, s/Fixed/Fix/ is the recommended phrasing.

[PATCH] ASoC: rsnd: Emit useful error messages in .remove()
by Uwe Kleine-König 06 Jul '22

06 Jul '22

If more than one call of rsnd_dai_call(remove, ...) fails the platform remove callback returns all values orred together which then makes the driver core emit a generic error message which is little helpful. Instead emit details of which call failed exactly and return 0. Note returning 0 instead of an error code doesn't make a difference in the driver core apart from the error message. This is a preparation for making platform remove callbacks return void.
