[PATCH] Revert "aplay: fix S24_LE wav header"
by Shengjiu Wang 13 Nov '24

13 Nov '24

S24_LE means the lower 24bit in 32bit space has valid data. So previous code is correct. The commit causes regression, then revert it. This reverts commit 9cdcbe0e932b97fac88a6195f87647159a6c7194.

While sound works "fine" (ish), it's limited to 2 channels. * Plugging in another USB device (CM106-type, for example) gives out a plethora of configuration options (per the screenshot), though this also comes with having to select the right output * The "USB" audio outs are output-specific, which is VERY welcome, but the S/PDIF out does not allow for any advanced selection like "Supported Codecs", and the HiFi 5.1 and 7.1 do not appear to enable any IEC958/AC3 support in the background Is there something missing in the config files to allow for such support? ### Relevant files & the such * [alsa-info info dump](https://github.com/user-attachments/files/17721762/alsa-info.txt) * Screenshot of the other USB device * ![image](https://github.com/user-attachments/assets/906ea829-0210-49a8-ba16-ad1b5b1285ae) Issue URL : https://github.com/alsa-project/alsa-ucm-conf/issues/462 Repository URL: https://github.com/alsa-project/alsa-ucm-conf
