Public bug reported: Hi. I am trying to use an onboard Realtek ALC255 soundcard to play audio files that are 192khz. The card supports sampling rates up to 192khz and the machine (Asus mini PC) successfully plays them at that rate under Windows. However, under Ubuntu 18.04(and Debian 10), the sampling rate is maxed out at 48 Khz.
Changing the Alsa configuration to force a higher sampling rate (or to play without resampling) has no effect. I tried to upgrade the Linux kernel to this one https://drive.google.com/drive/folders/16OBmEmWPYncLOT-QVlo6vkyy3Ar819aX (unsigned 5.021) as I hoped it contains custom drivers for ALC255, but the result is still the same. Any idea if this has been solved in any kernel version? regards Christo ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1867510 Title: Realtek ALC255 cannot play at higher than 48 khz - defaults to generic Intel driver?
