So I have checked this, starting with the Walkman connected in DAC=20 mode, so it is only seen in DAC mode. Pop OS updates the sound settings=20 so that the Walkman is the selected output device. It does not show as=20 muted. Within ALSA Mixer, I see that HDA Intel PCM is first, and then=20 the WALKMAN device, however when selecting WALKMAN I get "This sound=20 device does not have any controls". >=20 > Thanks, > Carsten > ----------------- > Siemens Electronic Design Automation GmbH; Anschrift: Arnulfstra=DFe=20 > 201, 80634 M=FCnchen; Gesellschaft mit beschr=E4nkter Haftung;=20 > Gesch=E4ftsf=FChrer: Thomas Heurung, Frank Th=FCrauf; Sitz der=20 > Gesellschaft: M=FCnchen; Registergericht M=FCnchen, HRB 106955 >=20 Kind regards, Neil
