I definitely confirm that this issue is NOT specific to AMD/ATI Tahiti XT, but
also appears with following NVIDIA hardware :

$ lspci -nn -v -s 1:0
01:00.0 3D controller [0302]: NVIDIA Corporation GP107M [GeForce GTX 1050 Ti
Mobile] [10de:1c8c] (rev a1)
        Subsystem: Micro-Star International Co., Ltd. [MSI] GP107M [GeForce GTX
1050 Ti Mobile] [1462:11c8]
        Flags: bus master, fast devsel, latency 0, IRQ 134
        Memory at de000000 (32-bit, non-prefetchable) [size=16M]
        Memory at c0000000 (64-bit, prefetchable) [size=256M]
        Memory at d0000000 (64-bit, prefetchable) [size=32M]
        I/O ports at e000 [size=128]
        Expansion ROM at df000000 [disabled] [size=512K]
        Capabilities: <access denied>
        Kernel driver in use: nouveau
        Kernel modules: nvidiafb, nouveau

Therefore, the origin of this issue could be the ALSA driver, and I will try to
report this issue at https://www.alsa-project.org
